SOCKS4

SOCKS4 is an older version of the SOCKS protocol that allows clients to connect to servers through a proxy server. Here are some key details about SOCKS4:

Key Features of SOCKS4:

• TCP Traffic Only: SOCKS4 only supports TCP connections, making it suitable for applications that rely on TCP but not for those requiring UDP.
• No Authentication: SOCKS4 does not support user authentication, meaning anyone can use the proxy without credentials. This can pose security risks.
• Simple Setup: It's easier to configure compared to SOCKS5, which makes it a straightforward choice for basic proxy needs.

Use Cases:

• Web Browsing: Can be used for browsing websites anonymously.
• P2P Applications: Useful for applications that utilize TCP for file sharing.
• Game Servers: Some online games can connect through SOCKS4 proxies for better performance or to bypass regional restrictions.

Limitations:

• Limited Features: Lack of UDP support and authentication means it may not be suitable for all use cases, especially those needing enhanced security or multi-protocol support.
• Less Popular: With the advent of SOCKS5, SOCKS4 is less commonly used today, as SOCKS5 provides additional features and better security.
