SOCKS4 proxies

SOCKS4 proxies route TCP traffic from almost any network application through an intermediate server. Operating at the transport layer, this protocol does not inspect packet contents and does not expose the user's real IP to the target server. SOCKS4 does not support UDP or authentication, but offers easy setup and low latency. Servers can be combined into chains for enhanced privacy.

When to choose SOCKS4 proxies

Typical use cases

  • TCP traffic proxying for any application
  • Basic IP masking
  • Working with legacy apps supporting only SOCKS4
  • Building proxy chains for routing
  • Testing network routes and latency

Limitations and comparison with SOCKS5

SOCKS4 does not support UDP traffic, IPv6, or login/password authentication. For gaming servers, streaming, VoIP, or IPv6 networks, SOCKS5 is the better choice. For pure HTTP traffic, HTTP proxies may be faster due to caching. Typical ports: 1080, 1081, 4145.

Frequently asked questions

What is a SOCKS4 proxy?

SOCKS4 is a transport-layer proxy protocol. It redirects TCP traffic from any application and does not expose the client IP to the target server. The protocol does not support UDP or authentication.

How does SOCKS4 differ from SOCKS5?

SOCKS4 only supports TCP connections and has no built-in authentication. SOCKS5 additionally supports UDP, IPv6, and login/password authorization, making it more flexible.

What are SOCKS4 proxies used for?

SOCKS4 proxies are used to mask IP addresses in TCP applications, bypass network blocks, work through proxy chains, and provide a basic level of privacy.

Are SOCKS4 proxies compatible with modern applications?

Most modern applications support SOCKS4, but if the application requires UDP, IPv6, or authentication, SOCKS5 is necessary.

What ports do SOCKS4 proxies use?

SOCKS4 proxies most commonly run on ports 1080 (SOCKS standard), 1081, and 4145. Port 1080 is the most widespread for all SOCKS proxy types.
