IP2World: Unravel the Mystery of SOCKS5, HTTP(S) Proxy Protocol for You!

Novices in the agency world are often confused when faced with a wide variety of agency agreements. The combination of simple English letters has become an intriguing noun. If you, like most people, are curious about the heavy words that often appear in the IP Proxies: SOCKS5, HTTP(S), this article will benefit you.

What is HTTP(S)?

At present, HTTP(S) is still the most widely used proxy protocol on the Internet. For example,, HTTP is the abbreviation of Hypertext Transfer Protocol, which is a protocol for transmitting data based on the TCP/IP protocol. Generally, the client initiates the request and the server responds. Although the process is simple and fast, it is less secure because of the clear text transport. Compared with HTTP, HTTPS is bundled with the encrypted transmission security protocol SSL (abbreviated as S), which enables the transmitted text to be encrypted, but greatly affects the loading speed, and the cost is relatively high.

What is SOCKS?

SOCKS is an Internet protocol that exchanges network packets between a client and server through a proxy server. (From Wikipedia)
It means that SOCKS is an Internet protocol that exchanges network data between the client and the server through a proxy server. In other words, it is a proxy protocol that acts as a middleman to convert data between the client and the target host.

In order to ensure security inside the enterprise network, a firewall is usually installed. In this way, although network security is guaranteed, data access to the external network is also blocked. In order to solve this problem, a SOCKS proxy server emerges at the historic moment, and it usually replaces the connection and data communication between the client and the target website.

What is SOCKS5?

SOCKS5, as the name implies, is the fifth session layer running in the OSI seven-layer protocol. As an extension of SOCKS4, UDP forwarding and authentication functions are added on the basis of SOCKS4. It can handle a variety of request types including HTTP, HTTPS, POP3, SMTP and FTP, and can use SOCKS protocol to send emails, browse web pages, transfer files, etc.

Compared with SOCKS4, SOCKS5 also adds an authentication mechanism, so a complete TCP connection can be established through authentication. SOCKS5 is usually used together with SSH to relay traffic by using the SSH encrypted tunnel method.

Use of SOCKS5:

First of all, we can access services behind the firewall through SOCKS5.
Generally speaking, for the sake of security, the server is placed behind the firewall, but if outsiders want to access the server, there are two ways. The first is to close the firewall and open the service to the outside, but this will bring security risks. The second is to filter illegal access requests by setting the client's IP whitelist. However, the IP address of the client usually changes, so this approach is not feasible.

If you use SOCKS5 SSH proxy, you can access the service behind the firewall through the proxy server, so as to ensure the security of the service.
Also, by setting up an SSH tunnel where the various TCP and UDP traffic is routed to their respective services using the SOCKS5 protocol, then only SSH is required and no other VPN network is required. So it is relatively simple to use.
Finally, because SOCKS5 only forwards data, there is less possibility of errors and higher performance.

The SOCKS5 proxy protocol performs best in the Internet. HTTPS is slightly inferior to it, but has better security than HTTP proxies.
The above are the main differences and characteristics of common proxy protocols. Here we recommend a reliable and affordable overseas SOCKS5 proxyβ€”β€”IP2World, which supports high-quality HTTP(S) and SOCKS5 proxy protocols. You can choose these two when generating proxies to speed up your business!
