Many people are unfamiliar with the Socks5 transmission protocol, which is different from the well-known HTTP, HTTPS, FTP and other transmission protocols. In fact, Socks5 only serves as an intermediate role to connect the client and external server, aiming to remove the restrictions on communication between different protocols and improve the security of the communication channel between the client and the Internet server.

The SockS5 protocol works similarly to HTTP, where requests are first sent to a proxy server and then forwarded to an external server by the proxy server. After confirming the correctness of the external server, the result is returned and the user can view it on the device. At this point, the process ends.

Due to its simplicity and efficiency, the SockS5 protocol is widely used in the field of network technology, mainly in network security, user privacy, and bypassing access restrictions by accessing pages with hidden addresses that pose security risks.

For example, when you visit an overseas website, due to geographical restrictions, the new page you are redirected to will not refresh with new content, but instead display a page error issue. At this point, there is a security gateway that blocks communication between you and the target website. In this gateway, your request is parsed and reviewed. When the review finds any inappropriate content, the request is rejected and the client receives a page error code indicating that it cannot be accessed.

The SockS5 protocol can to some extent avoid this problem. When you send a request, the SockS5 protocol encrypts the data. During the review process, if the security gateway cannot recognize the encrypted content, it will redirect the request to the target website, and the user can successfully access the target website.

In IP proxy, Socks5 protocol plays a very important role, and its advantages are very obvious. It can help users quickly achieve network communication and is widely welcomed by users.
