A comprehensive review of common IP proxy protocols and standards

In our daily life on the Internet, we often encounter situations where we need to use proxy IPs, such as when conducting online research, crawling data, or circumventing network restrictions. However, the protocols and standards behind these proxy IPs may vary. So, what are the common IP proxy protocols and standards?

1. HTTP Proxy

HTTP proxy is one of the most common proxy protocols, which communicates via the HTTP protocol. HTTP proxy is usually used for web browsing and network requests, and can handle HTTP connections, requests, and responses. When using HTTP proxy, the client establishes a connection with the proxy server, and then the proxy server forwards the request to the target server and returns the target server's response to the client.

HTTPS Proxy

HTTPS proxy is an upgraded version of HTTP proxy. It communicates through the HTTPS protocol and provides a more secure network connection. HTTPS proxy can encrypt the communication between the client and the proxy server to protect the user's privacy and data security.

3. SOCKS Proxy

SOCKS proxy is a more general proxy protocol that supports multiple network protocols, such as TCP, UDP, etc. SOCKS proxy communicates through the SOCKS protocol and can be divided into two types: SOCKS4 and SOCKS5. SOCKS4 only supports TCP protocol, while SOCKS5 supports TCP and UDP protocols and provides more features, such as authentication and protocol negotiation.

4. Tor Proxy

Tor (The Onion Router) proxy is an encrypted communication network that protects the privacy and security of users through multiple encryption and routing. Tor proxy can hide the user's real IP address and geographic location, making network requests difficult to track and monitor. However, Tor proxy is relatively slow and may not be suitable for application scenarios that require high speed.

5. VPN Proxy

A VPN (Virtual Private Network) proxy is a virtual private network that can establish an encrypted channel on a public network, making the communication between the client and the target server secure and reliable. A VPN proxy can provide a virtual private network connection, allowing users to remotely access internal network resources while protecting user privacy and data security.

6. Shadowsocks Proxy

Shadowsocks is an encrypted proxy software that can establish an encrypted channel between the user and the target server, making the network connection safe and reliable. Shadowsocks supports a variety of encryption algorithms and protocols, and can flexibly adapt to different network environments and needs. However, the use of Shadowsocks requires certain technical knowledge and configuration capabilities, so it is not suitable for ordinary users.

The above are the common IP proxy protocols and standards. Different proxy protocols and standards have different characteristics and applicable scenarios. Users can choose the appropriate proxy method according to their needs. When using a proxy, be sure to protect your privacy and data security.
