A SOCKS5 proxy is an alternative to a VPN. Usually, SOCKS5 proxies route packets between a server and a client using a proxy server. What does that mean? This means that your real IP address is hidden and you access the internet with an address provided to you by a proxy provider. It functions like a proxy because it is a type of proxy.

Advantages of Using SOCKS5 Proxy Servers

• A SOCKS5 proxy helps you get around internet blocks by acting as a relay between your device and the internet, bypassing internet blocks.
• SOCKS5 proxy servers are faster and more reliable connection. Unlike its predecessors, which only used TCP protocol, SOCKS5 proxy servers can use UDP protocol, ensuring a reliable connection and efficient performance.
• If you use the SOCKS5 proxy, you will encounter fewer errors and improved overall performance. Many other proxies rewrite data packet headers. Because of this, there’s a high chance of misrouting or mislabeling that data.
• SOCKS5 proxy servers offer better performance on P2P platforms — they are faster than other proxies because it transfers smaller data packets. Therefore, SOCKS5 proxy servers offer faster download speeds, which is why many users use them to connect to P2P-sharing websites and platforms.

How To Set Up a SOCKS5 Proxy Manually on Windows 10

1. Go to “Settings” > “Network & Internet” > “Proxy.”
2. Under “Manual proxy setup,” toggle the “On” button.
3. Fill in details about your proxy server.
4. Click “Save.”

How To Set Up a SOCKS5 Proxy Manually on macOS

1. Go to “System Preferences” > “Network” > “Advanced” > “Proxies.”
2. Select the “SOCKS proxy” protocol in the menu.
3. Type your proxy server address.
4. Click “OK.”

A free socks5 won’t be useful. rather it is very dangerous.
Because it would be shared, and probably datacenter proxy not a residential proxy. So it would have 100/100 fraud score, it would only slow down your internet, and make all websites treat you like a cybersecurity for the high fraud score.

The better is use a dedicated residential proxy. There are some providers sell it for 3 dollars only a month.

The residential proxy comes from a real internet device provider(ISP) like Comcast, spectrum. etc.

You should check the residential proxy fraud score if you buy dedicated one.

There are some providers sell dedicated residential proxies stable or rotation proxy.

While some providers allow you to change the proxy but it would a shared proxy someone else might be abused it.

Thats why I prefer the dedicated residential proxies. Because they are Virgin too and nobody else used them before.

I'm able to SSH SOCKS tunnel to my server in Hong Kong although it's occasionally unstable if I try to push too much data through it (e.g. downloading a lot of online video) possibly because they monitor and limit the amount of encrypted traffic over a particular IP/port.

It's very possible, then, that you're experiencing a problem getting proper DNS resolution. I would recommend installing DNSCrypt, a free encrypted DNS service by OpenDNS. You can download it here: DNSCrypt

This encrypts your DNS queries so that there is no DNS cache poisoning or GFW blocks for domain name resolution.

If you're a Chrome user, I would also recommend installing the Switchy Sharp plug-in that allows you to configure your SOCKS proxy on a domain-by-domain or regex pattern match basis. This helps to limit the total amount of traffic you send over to your relatively slower proxy server.

HTTPS proxies have a few distinct advantages over HTTP, SOCKS4 and SOCKS5 proxies especially when it comes to security. First off the key difference with HTTPS is that it encrypts your traffic. This means that whatever data you're sending or receiving is protected from prying eyes. If you’re doing anything sensitive online like entering passwords, banking info or handling confidential documents this encryption is crucial. It keeps you safe from cybercriminals which can be a serious concern if you’re using an HTTP proxy since those don’t encrypt traffic at all. SOCKS5 is more flexible and can handle more types of traffic than HTTPS but it doesn't inherently encrypt data so it can't match the security level of HTTPS.

I remember this one time when I was setting up a small project with a client. We were testing various proxies to see which worked best for accessing certain restricted resources. Initially we tried using an HTTP proxy but halfway through the project we started noticing some weird activity. Turns out our unencrypted data was being intercepted. We quickly switched to an HTTPS proxy and the difference was night and day. Not only was our data safe but the speed remained solid. Plus it was a relief knowing sensitive info wasn’t at risk. That little switch saved us a lot of headaches and trust me you don’t want to learn that lesson the hard way.

SOCKS proxy is an additional feature that some VPN providers offer, allowing users to fake their virtual location (also known as location spoofing)

. A SOCKS5 proxy allows you to hide your IP address from online services.

Socket Secure (SOCKS) is a protocol used for proxy servers.

“Socket Secure (SOCKS) is an Internet protocol that exchanges network packets between a client and a server through a proxy server. Practically, a SOCKS server proxies TCP connection to an arbitrary IP address, and provides a means for UDP packets to be forwarded.“

There are more versions of Socks web proxies available but Socks5 is its extension which is considered to be the most flexible server protocol because it can’t differentiate network traffic types (FTP for torrent files, HTTP for web browsing, SMTP for email, etc.).

In simple words, a Socks proxy works as a bridge between your device and the Internet. In this way, all the traffic generated while using this proxy server can’t be associated with your real IP.

An important thing to mention is that Socks5 is popular among users who don’t require a high level of security and don’t want to connect securely. In other words, the Socks5 proxy server will change your real IP but will not encrypt your traffic.

Socks5 proxy vs. HTTP proxy.

The most common protocol on the internet is the HTTPS, the secure extension of the HTTP protocol (HyperText Transfer Protocol).

As the name suggests, the HTTP proxies work together with the HTTP protocol, while sending data over the internet.

An HTTP proxy features built-in encryption and is a good solution for unblocking specific geo-blocked content, but the proxy connection doesn’t work so well with other protocols.

Compared to the HTTP proxies, the Socks5 works well with different protocols. Also, the SOCKS server does not interpret the traffic between a device and the server in any way. This is the reason why is a good solution for clients behind a firewall who can’t establish TCP connections to servers outside the firewall.

Socks5 vs. VPN

A VPN (Virtual Private Network) is gaining a lot of well-deserved attention these days.

The VPN provides a secure way to keep users internet connections safe. To be more specific, the VPN technology will add a layer of encryption to your internet connection while surfing the web. In more simple words, a VPN will pass all your data via a VPN server, before transmitting your request to the internet. In this way all your data is encrypted, your connection is secured, and your real IP is hidden.

This technique prevents your ISP from being able to see in the plain text your online activities, including the websites you open and any data you send and receive so, we can conclude that a VPN will highly contribute to your online privacy and security.

If you’re wondering when to use a VPN connection, the answer is ALWAYS, no matter if you’re connecting to public or private networks.

So, what’s better? Socks5 or a VPN?

A VPN changes your IP address and also creates a secure tunnel between you and the VPN server. All the applications from the computer are using the encrypted tunnel when the VPN is connected.

Socks5 changes your IP address and is faster than VPN, but doesn’t encrypt the traffic. Only selected applications are using Socks5 (browsers, torrent apps).

When it comes to downloading torrents, both solutions are helping you but, in this case, the VPN is the winner because it encrypts your connection. Also, a VPN should provide your P2P servers, so you can download torrents in a legal manner.

For a better and faster way to understand the similarities between these two technologies, check out the image below.

The advantages and disadvantages of Socks5.

Advantages of using Socks5:

• Ideal for torrent – masks your IP address and it has a great performance for torrents and P2P;
• Faster than VPN – the speed is not affected because there is no encryption;
• Easy to configure – can be configured with almost any program;
• Torrent Protection – some torrent apps stop downloading if Socks5 connection is not active;
• Bypass censorship and firewalls – get around IP blocks that are based on IP restrictions;
• Efficient connections – Can use both TCP protocol and UDP protocol.

Disadvantages of using Socks5:

When it comes to speaking about the disadvantages of a Socks5 proxy, the most important thing to mention is the lack of encryption.

Even if for some users this is not a huge inconvenient, for the ones preoccupied with online privacy and security matters, using a Socks5 proxy is definitely not an option.

Why and when to use Socks5?

Now that we know what is Socks5 proxy let’s draw a conclusion about why and when Socks5 come in handy.

A Socks5 proxy is a useful tool in case you need to change your IP fast and easy. The technique of changing your IP helps you bypass restrictions or access geo-blocked content.

Keep in mind that even if this proxy does to your connection the same thing as the VPN, Socks5 won’t encrypt your traffic before sending your data to the webserver and your online activities will be exposed. Also, the lack of encryption won’t affect the overall performance of your connection.

While the VPN is the top choice of users who seek to protect their online privacy, the Socks5 proxy is preferred by the users who download torrents. Even if Socks5 won’t affect your download speed, our suggestion is to take into consideration the option of downloading torrents by using a VPN, while being connected to a P2P server. This thing will keep you safe because the P2P servers are located in countries where the torrent download is legal or is not regulated.

How to test the Socks5 proxy’s performance?

If you’re ready to test the performance of the Socks5 proxy, ibVPN is a good choice.

After years of hard work and dedication, we can say that we are a VPN provider praised all over the world for the quality of service and support we are offering. Our customers’ reviews speak for us.

Currently, we are offering a VPN, SmartDNS and proxy solution for all the folks looking for the right provider to meet their needs.

During the years we were able to develop VPN apps compatible with different operating systems that work fast and easy.

Back in 2016, we were proudly introducing our Socks5 proxy feature. This feature helps our users download torrents safe and easy. For this purpose, we’ve put together some tutorials about:

Socket Secure Proxies (or SOCKS) are often confused as an alternative or equivalent to private virtual networks. This also leads to ambiguity and misunderstandings for computer users.

SOCKS is an internet protocol that provides more anonymity than was initially established. Once you connect to a SOCKS proxy, the traffic through the Transmission Control Protocol ( TCP) is redirected to a third-party server. A brand new IP address is assigned to you during this process , meaning that the web host can not flag down exactly your physical location with this change in your IP address.

In situations involving bypassing regional filters, SOCKS proxies are suitable. However, you can have to look elsewhere if you are on the lookout for encryption. Setting up a SOCKS protocol alone will not guarantee privacy and prevent government surveillance or public Wi-Fi attacks. Because not all applications are running it is not necessarily safe regular browsing.

A. SOCKS Proxy Working Method

Proxies are wider than conventional proxies. Socks are more commonly available. One way of knowing the degree of the OSI is to learn the OSI model.

The OSI model is a reference model developed by the IEEE Committee of the Institute of Electric and Electronic Engineers in order to promote the cooperation between different suppliers and products. It has 7 tiers from the lowest to the highest, this model consists of :

• The Physical Layer
• The electrical signaling interface responsible for the transmission of the raw-bit stream
• The Datalink Layer
• Responsible for flow control Hardware management This is the location of frames
• The Network Layer
• The way systems are located in this layer on different networks: subnet route IP & IPX protocols used here
• The Transport Layer
• Break data into frames Defines sequence numbers Sequence numbers Tests for SPX and UDP obtained data work here
• The Session Layer
• Responsible for connection development and maintenance, also responsible for ports
• The Presentation Layer
• Ensures that the functional data encryption is executed here when data is obtained
• The Application Layer
• Determines when network access is needed.

SOCKS proxies are in this model's higher level. It is in the 7th tier below SSL, but above such stuff as TXP and UDP on the transport layer. In order for all packets to arrive at their destination, it can form physical connections to the client and the server as they were sent.

Cryption is not managed by SOCKS. However, it can include a few authentication methods. Such will be the average instance of use by SOCKS:

1- A connection request starts by sending a client
——-This request includes a list of supported authentication methods
2- The servers then evaluate and choose the methods they are suitable for.
——- If no acceptable method is found, a failure reply is sent.
3- If everything goes well, information is transmitted between client and server if everything is accepted.
——- Client sends requests for connection; server answers

B. Different Types of SOCKS Proxies

• SOCKS4

SOCKS4 was the first SOCKS protocol widely accepted version. This first iteration came with some warnings :

a. No authentication was needed, all that it took was a username for a client to access SOCKS4 services.

b. The customers had to know the server IP addresses they wanted to connect to; this meant that they also had to patch domain names.

• SOCKS4A

The first problem with SOCKS4A described above was a simple solution. SOCKS4A was planned.

• SOCKS5

The latest SOCKS5 version is the SOCKS Standard. The newest edition. In its original iteration, SOCKS5 solved both of the issues affecting SOCKS4. To improve protection, an extensible authentication scheme has been introduced, featuring a trio of authentication methods.

1. Null Authentication
2. Username/Password Authentication
3. GSS-API Authentication

C. SOCKS Safety Level

You can also login and search anonymously through SOCKS proxies. They act as an intermediary in a way that hides your legal place information and IP address in order to avoid tracking you. So your SOCKS proxy would take over, and use a different IP address, rather than using your own IP address to connect to online servers.

Such proxies connect to the internet through a tunneling mechanism. Tunneling is generally regarded as one of the safest means of connecting to the internet and accessing it. It is definitely safer than modern, normal HTTP proxies. To communicate with the internet, HTTP proxies use an open port. As tunnels do not form links they are easily disintegrated and penetrated into these proxies. Proxies from SOCKS do not have this problem.

Some proxy enterprises are known for logging user data. This should not be a concern when using a premium SOCKS proxy service. Your information will be safe and secure – so you can work without worries.

D. SOCK Proxies Common Usages

Proxies from SOCKS are perfect choices for firewall scenarios. As the network flowing between client and server is not interpreted by the SOCKS servers, they are often used in situations where clients are behind a firewall. This implies, if clients do not use SOCKS software, they can not create TCP connections to servers outside of this firewall.

The vast majority of the web browsers can be easily configured to communicate with web servers through SOCKS servers (after some research). Because clients have to connect first to SOCKS servers and let the host know where they are going to connect, they should be "SOCKS enables."

Since SOCKS servers are proxy servers for general purposes, they are also used in numerous everyday applications. Their compatibility with any type of network protocol on any port gives them a multitude of situations that are easy to use.

E. SOCKS vs. VPN

As mentioned above, it is not unusual to confuse SOCKS proxies and VPNs by the average computer user. Both mask your IP address from your prying eyes, it may seem to the layman the one thing that only you have to worry about when you look for safety.

However, this calculation also contains other variables. Proxy servers, for example, do not encrypt traffic completely. SOCKS proxies are therefore generally accepted to run faster. As they do not need to use resources to encrypt data, the download and upload speeds are typically higher than those of VPN solutions.

The SOCKS proxies and VPNs vary from each other. The choice between a VPN or SOCKS proxy is generally considered to be the choice between privacy and speed.

After all, the use of a VPN would offer an internet user more privacy and more protection. The end-to - end encryption tackling the VPNs actually keeps you safe, preventing your internet activities from being monitored by ISPs, government agencies, advertisers and anyone else. Just SOCKS covers who you are, specifically.

When choosing between a SOCKS proxy or VPN, a few things should be remembered:

a. Both options hide your IP address and disguise your web identity.

b. SOCKS proxies do not encrypt your traffic.

c. The use of SOCKS proxies for can P2P applications gives you the ability to better browse and update than a VPN.

d. Your ISP can still monitor your downloading activities if you want to use SOCKS proxies

e. In the meantime, VPN provides absolute anonymity and concealment.

F. Conclusion

There's great news for those of you who don't want to choose between the two: you don't have to! Some VPN services can use both SOCKS and VPN proxies. Many of these also make it possible for you to benefit from these double benefits at no extra expense.

Everyone who hunts for more complete safety offers and more tranquility is best served by the use of a VPN. To those who want to add encryption to their browsing activities, SOCKS proxies are the ideal alternative, but VPNs are the easy choice to keep their company online in complete privacy.

Very simple, I use VPN to set up SOCKS5 proxy

Below I will elaborate on how to set up Google Chrome Socks5

The Socks5 protocol is a local proxy based on TCP protocol, which without affecting the default network environment of other software.

1. Open VPN—Settings—Switch Socks5 Protocol—Connect

2.Get the local IP address and port number through VPN

3. Open Google Chrome - download the proxy plugin, such as "SwitchyOmega" - complete the installation

4. Run "SwitchyOmega" - click on "Options"

5. Select "proxy" - select "Socks5" protocol - enter FlyVPN proxy server, proxy port—Save

6. Complete the setting

Note: If IE/Chrome uses the system default proxy settings, then access to the restricted website is not allowed. You need to install a separate proxy switch plugin to use the Socks5 proxy. It is recommended to install a proxy switch plugin such as Proxy Switcher.

There are several ways to set up a SOCKS5 proxy. The easiest being the -D option with SSH.

ssh username@remotehost -D 1080

This sets up a SOCKS proxy on localhost:1080 (if you want it to listen on all ports, use :1080)

The next best way is if you want to surf the dark web, install The Onion Routing (TOR) which sets up a socks proxy on your server, typically port 9050. It will allow you to surf the public internet as a Proxy server and surf the dark web if you have DNS set to resolve through the Socks Proxy (not on by default; on Firefox about:config -> network.proxy.socks_remote_dns; set to true).

If you want to actually use your SOCKS proxy, you have to set it up. In Firefox, Edit-Preferences->Network Settings>Manual Host Configuration -> Socks Host (127.0.0.1) -> Port (designated port).

A SOCKS5 proxy is an alternative to a VPN. Usually, SOCKS5 proxies route packets between a server and a client using a proxy server. What does that mean? This means that your real IP address is hidden and you access the internet with an address provided to you by a proxy provider. It functions like a proxy because it is a type of proxy.

An HTTP proxy acts as a high-performance content filter on traffic received by an HTTP client and HTTP server. The HTTP proxy protocol routes client requests from web browsers to the internet and supports rapid data caching.

HTTP proxies do not use the SSL protocol. These proxies have some great niche applications, that are hindered by the SSL. These are the basic types of proxies that may or may not have subtypes. For instance, elite proxies are a type of HTTP proxies.

HTTP Proxies Vs. SOCKS5 Proxies

• Functionality: HTTP proxies have decent load speeds and are better for managing data transfers based on time rather than quantity. SOCKS are very quick, making them ideal for internet-based data routing.
• Use Cases: They can be used to cache or filter content and collect data via browsers. Typically used to stream web content as well as file sharing using peer-to-peer methodologies. Additionally, they can help access targets that sit behind a firewall as they are flexible and not dependent on any one protocol.
• Security: Can be used to add an additional level of security between the ‘user’ and the ‘client’. Enabling systems to better protect themselves from malicious external threats. Do not employ tunnel encryption found in other alternatives and may impact levels of security in the context of certain use cases. SOCKS5 also includes data packet headers decreasing errors but exposing more of your personal information.
• Integration: HTTP proxies connect with virtually any tool. SOCKS5 connects with a more limited pool of tools.

Because I currently use FlyVPN, I use it as an example to illustrate how to configure the Socks5 proxy in Firefox.

1. Open FlyVPN—Settings—Switch Socks5 Protocol—Connect

2. Get the local IP address and port number through FlyVPN

3. Open Firefox - click on "Menu" - click on "Options" - find "Network Settings"

4. Click "manual proxy configuration (M)"— select the corresponding option —Enter FlyVPN Proxy Server, Port Information—Save

5. Complete the Setting

Let’s consider, first, what is proxy. The dictionary meaning of the word is “authority given to someone to act for you”. A proxy server is a computer that connects to target servers on the behalf of your computer. When you want to connect to a server, you do not directly connect to the target server; instead, you connect to a proxy server that will connect to the target on your behalf.

You may raise the question, Why do you want to use another server( proxy ) to connect to a target? Other who are aware of the issues of giving authority to someone may wonder, how do a proxy server authenticate computers that connect to it? and how do a proxy server know which target a client wants to connect or get the data a client wants to send to the target.

Why do you want to use another server( proxy ) to connect to a target? This is a generic question pertaining to “proxy” that you need to be able to answer, if you were to understand what a proxy is. Other Quora members post good answers to this question.

A proxy server is SOCKS5 when it is compliant to the SOCKS5 protocol specification. A client just cannot connect to a server and send it arbitrary data; the server will not understand what the client wants to do. A client must follow SOCKS5 protocol to use SOCKS5 proxy; it needs to authenticate to SOCKS5 server and send/receive data according to SOCKS5 protocol.

You can communicate with a destination server via SOCKS5 proxy, regardless of what data you want to send/receive. A client can send a block of binary data to SOCKS5 which, then, communicate with the destination server just as the client directly would. A browser can communicate with SOCKS5 server which receives requests from the browser, send them to target servers, receives responses and finally forward the responses to the browser.

Another important question would be, How secure is the connection between a client and a SOCKS5 server? If you want the connection to be secure, look into SOCKS5 server comprising of SSH client and SSH server. SSH client acts as SOCKS5 server and communicate with SSH server over a secure channel. SSH server connects to destination servers on client’s behalf.

A SOCKS5 proxy is an alternative to a VPN. Usually, SOCKS5 proxies route packets between a server and a client using a proxy server. What does that mean? This means that your real IP address is hidden and you access the internet with an address provided to you by a proxy provider. It functions like a proxy because it is a type of proxy.

5. Click Save. The new SOCKS5 server profile is listed in the side panel.

In computer networks, a proxy or proxy server is a computer that sits between you and the server. It acts as a gateway between a local network and a large-scale network, such as the internet.

A proxy server works by intercepting connections between sender and receiver. All incoming data enters through one port and is forwarded to the rest of the network via another port.

Aside from traffic forwarding, proxy servers provide security by hiding the actual IP address of a server. They also have caching mechanisms that store requested resources to improve performance. A proxy server can encrypt your data so it is unreadable in transit and block access to certain webpages based on IP address.

Socks (or "SOCKS") is a protocol that a proxy server can use to accept requests from client users in a company's network so that it can forward them across the Internet. Socks uses sockets to represent and keep track of individual connections. The client-side of Socks is built into certain Web browsers and the server-side can be added to a proxy server.

A socks server handles requests from clients inside a company's firewall and either allows or rejects connection requests, based on the requested Internet destination or user identification. Once a connection and a subsequent "bind" request have been set up, the flow of information exchange follows the usual protocol (for example, the Web's Hypertext transfer protocol).

How do SOCKS work exactly?

The most obvious way to use the SOCKS proxy is when a client behind the firewall wants to create an outgoing connection via the SOCKS proxy when the firewall rules are blocking outgoing connections.

SOCKS5 proxy is an alternative to a VPN. Usually, SOCKS5 proxies route packets between a server and a client using a proxy server. What does that mean? This means that your real IP address is hidden and you access the internet with an address provided to you by a proxy provider. It functions like a proxy because it is a type of proxy.

Uses of SOCKS5 Proxy

• Gets you around internet blocks
• Faster and more reliable connection
• Fewer errors and improved overall performance
• Better performance on P2P platforms

Advantages of Using SOCKS5 Proxy Servers

• A SOCKS5 proxy helps you get around internet blocks by acting as a relay between your device and the internet, bypassing internet blocks.
• SOCKS5 proxy servers are faster and more reliable connections. Unlike its predecessors, which only used TCP protocol, SOCKS5 proxy servers can use UDP protocol, ensuring a reliable connection and efficient performance.
• If you use the SOCKS5 proxy, you will encounter fewer errors and improved overall performance. Many other proxies rewrite data packet headers. Because of this, there’s a high chance of misrouting or mislabeling that data.
• SOCKS5 proxy servers offer better performance on P2P platforms — they are faster than other proxies because it transfers smaller data packets. Therefore, SOCKS5 proxy servers offer faster download speeds, which is why many users use them to connect to P2P-sharing websites and platforms.

SOCKS5 has enhanced security and offers three types of authentication methods:

• Null authentication – No authentication is required to connect to a proxy;
• Username/password authentication – You need to provide login details to connect to a proxy;
• GSS-API authentication – Both you and the server use authentication methods at the operating system level to verify your identity.
