On the modern Internet, anonymity is becoming increasingly important and more and more people begin to think about what tools they can use to protect themselves.
This is often confusing because not everyone understands the aspects of the existing technologies. Also, there are a lot of them and even hiding the real IP address can be performed by several different methods and tools.
SOCKS5 is one of the most effective tools on the market. This guide will walk you through the basic aspects of the technology and some popular questions about it. Also, we will review the best SOCKS5 proxy providers.
1. Internet protocols
Let’s start at the beginning. The Internet is basically built on three protocols:
- Internet Control Message Protocol (ICMP)
- Transmission Control Protocol (TCP)
- User Datagram Protocol (UDP)
ICMP is a control protocol. This means that it was not designed to port application data, but rather to provide information about the network state.
The best-known example of ICMP in practice is the ping utility. The protocols that are important in our case are TCP and UDP. Both TCP and UDP are transport protocols designed for data transfer. What is the difference between TCP and UDP? TCP virtually guarantees that all sent data reaches its destination in the correct order and performs other optimization and error checks.
In the case of UDP, it is a protocol without establishing a connection. Data that reaches its destination may arrive without an order, or it may not arrive at all. Typically, this type of connection is used for real-time data exchange where data delivery speed is preferable compared to getting the right data. So, where is the SOCKS proxy? Let us first look at what SOCKS is.
2. What is SOCKS?
SOCKS is an Internet protocol that allows one device to send data to another via a third one. In other words, this third device will be called a SOCKS server or SOCKS proxy server.
So, what does a SOCKS proxy server do? It makes a connection to any other server behind the firewall and exchanges network packets between the client and the actual server. Your traffic flows through a proxy server that assigns an arbitrary IP address before it reaches its destination. Technically speaking, SOCKS5 (the latest version) uses proxy servers to form UDP or TCP connections through arbitrary IP addresses.
If your IP address is 220.127.116.11 and the traffic is routed through a SOCKS proxy server with an IP address of 18.104.22.168, the destination server (website) will think the request came from the latter.
The website does not see your real IP address. This provides anonymity but does not mean that your traffic is secure. Unlike VPN, proxy servers do not encrypt your traffic — it is still open and anyone can spy on what you do.
3. What is SOCKS5?
SOCKS5 is the latest and the most advanced SOCKS protocol. It provides enhanced security and offers the following three types of authentication methods:
- Null authentication — no authentication required to connect to a proxy server;
- Authentication by login/password — you need to provide login details to connect to the proxy server;
- GSS-API authentication — both you and the server use operating-system-level authentication methods to verify your identity.
SOCKS proxies are usually needed where TCP connections are not allowed and the data can only be accessed via UDP. Unfortunately, in some cases, this connection is usually used for illegal reasons such as streaming.
4. Advantages of SOCKS5
Bypassing website blocking. The most obvious use of SOCKS5 proxies is to hide the real IP address for some purpose, for example, to bypass corporate or government restrictions. For example, if a certain IP address is blacklisted by a site, it will be enough to use a proxy to access it. In some cases, using this method, you can bypass the restrictions imposed by government agencies.
However, there are some limitations — when using DPI (deep packet inspection) technology, traffic will be blocked by the Internet service provider before it reaches the site. In this case, using only a proxy will not help. Keep in mind that some HTTP proxies can only handle web pages, while SOCKS5 ones can handle any type of traffic. Such proxies work at a lower level.
There are no traffic restrictions. Unlike HTTP proxies that can only interpret and handle HTTP and HTTPS web pages, SOCKS5 proxies can handle any traffic. HTTP proxies are high-level proxies usually designed for a particular protocol. This means that you get a better connection speed. HTTP proxies are not as flexible and secure as SOCKS proxies. SOCKS proxies are low-level proxies that can work with any program, protocol, and traffic.
Fast and reliable connections. Unlike previous versions of the technology which used only the TCP protocol, SOCKS5 proxies can use the UDP protocol. It provides reliable connections and efficient operation. The TCP protocol creates a connection between the client and a server, guaranteeing that all packages arrive from one side to another. For easy content transfer, a fixed format is required.
UDP does not focus on whether all packets from the client or server reach the other side and whether they are transmitted in the same order. UDP does not spend time converting data packets to a fixed packet stream. Therefore, with UDP at hand, SOCKS5 can offer higher speed and more reliable connections.
Fewer errors and better performance. Many other proxies overwrite the data packet headers. Because of this, there is a high probability of misdirection or incorrect data designation. SOCKS5 proxies do not overwrite data packet headers, so the error probability is much lower, and therefore, performance is automatically improved. Also, it highly improves your privacy and security because packet headers contain your personal information and can be easily identified.
Better performance on P2P platforms. SOCKS5 is faster than other proxies because they transmit smaller packets of data. Therefore, they provide faster download speeds so many users use them to connect to P2P sharing websites and platforms.
5. Which proxy is better: HTTP or SOCKS?
There are many types of proxies, but the most popular ones are HTTP or SOCKS. They have different characteristics, including indicators of anonymity, how information is transmitted to the user, and other features. To find out which type of proxies is better, take a closer look at the functionality they offer to satisfy the user’s needs.
6. HTTP proxies
HTTP is a standard and, at the same time, a common proxy version used in web browsers. It is considered outdated because it can only support an unsecured protocol. This is the main difference between HTTP and SOCKS. The HTTP proxy:
- restricts access to web resources, reduces connection speed;
- filters data on a web resource;
- caches the data, so that it saves a copy of the resource and issues it with the new request, to reduce the load on the channel and speed up the loading speed.
It works quite simply. The browser requests to visit some site, the server takes the required information from the requested resource and passes it to the end-user.
7. SOCKS5 proxies
At present, SOCKS is considered the preferred protocol to transfer data. It was created for programs that do not directly use an intermediate server and has highly improved over the years. It is better to work with the SOCKS server if you need a faster connection. There are several versions of the protocol available. However, SOCKS5 is the latest and recommended one.
The difference between HTTP and SOCKS is that the latter is anonymous by default, as it skips network traffic without making any changes or opening HTTP headers. That’s why the server that the user is requesting access to won’t know that you use proxy usage and won’t get your real IP address. At the same time, the app will establish connections that will look like you work directly with the website.
8. SOCKS5 vs HTTP
To make the right choice, you should know the difference between HTTP and SOCKS. The main difference is the way you work with large amounts of data. HTTP applies common network traffic processing and transmission schemes:
- tunneling, where data and functions of several network protocols are packed into one component;
- caching, by creating an intermediate buffer where the data is stored.
At the same time, SOCKS5 processes absolutely all network traffic without sending it to the user. This reduces the number of packets thrown into the external network and reduces the risk of detecting the IP address. They are also used in different ways. The HTTP proxy is used to work with network resources through a browser, while the main purpose of SOCKS is to ensure compatibility with other protocols.

9. SOCKS5 vs VPN
Not all proxy providers write about it, but the main difference when using SOCKS5 and VPN is the level of anonymity each of them can achieve. In the case of a VPN, all transmitted data is encrypted, which is not the case with SOCKS5 proxies. It is important to understand that proxies allow you to hide an IP address and perform a few other tasks (such as bypassing locks), but they are not a privacy tool by nature.
Proxy users can be tracked and their traffic intercepted. However, using a proxy in combination with a VPN allows you to achieve good speed and better protect sensitive information. VPNs provide more stable connections, while proxy connections can drop more frequently. At the same time, when the proxy connection drops, you cannot transfer data. In the case of a VPN, you go on working with your direct connection without protection.
9.1 Will a free VPN work?
You should avoid using free proxies, as well as free VPNs. Here is why:
- Poor performance. Free proxies will have lower support, lower configuration parameters, or slower infrastructure.
- Privacy issues. If you do not pay for the service, you are not a customer. Free proxies can track user traffic and sell this data to third parties.
- The best choice is a first-class proxy that offers the best speed, support, and security.
10. Pros and cons of SOCKS5 proxies
- You can use them to transfer all kinds of traffic, not just web pages.
- It provides a great level of anonymity. The proxy will assign you a new IP address and will not disclose your original data.
- They provide high performance so you can use SOCKS5 proxies with traffic-intensive applications.
- They do not encrypt your traffic so avoid using them to transfer sensitive data.
- Not all applications support them.
- They are more expensive than HTTP proxies.
