UDP Proxy Support

anyIP proxies support UDP (User Datagram Protocol), enabling advanced use cases like HTTP/3, QUIC, and modern streaming protocols.

🕵️‍♂️ Enhanced Stealth

Using UDP proxies significantly improves your stealth profile. Modern browsers and apps increasingly rely on UDP-based protocols (like QUIC/HTTP3).

• Blend In: Most real residential traffic uses QUIC. If you force TCP-only (HTTP/1.1 or HTTP/2), your traffic pattern looks distinct from regular users.
• Modern Footprint: Supporting UDP makes your bot or scraper indistinguishable from a standard Chrome or mobile user.

🚀 How UDP Support Works

Unlike TCP, which is connection-oriented, UDP is connectionless and often used for speed-critical applications (VoIP, gaming, streaming).

• Protocol: UDP is supported ONLY via SOCKS5.
• Port: Same port as TCP (1080).
• Authentication: Standard username/password authentication works for UDP.

Compatibility Warning

Not all proxy clients or software support UDP over SOCKS5. Many standard HTTP libraries (like Python requests or standard curl) do not support UDP proxying.

🛠 How to Test UDP Compatibility

The best way to test if your setup is correctly tunnelling UDP traffic is to check for HTTP/3 (QUIC) support, which runs exclusively over UDP.

Step-by-Step Test

1. Configure your browser or client to use our proxy via SOCKS5.
2. Visit this test page: https://cloudflare-quic.com/
3. Check the result:
   • Success: You see the message: “your browser used HTTP/3”.
   • Failure: You see: “your browser used HTTP/1.1” or “HTTP/2”.

Reload Required?

Browsers often attempt TCP/HTTP2 first. If you don’t see HTTP/3 immediately, reload the page a few times to force the browser to switch to the QUIC protocol.

Why am I seeing HTTP/1.1 or HTTP/2?

If the test page shows HTTP/1.1 or HTTP/2, it means your connection is falling back to TCP. This usually happens because:

• Your proxy client is configured for HTTP instead of SOCKS5.
• Your software/browser does not support UDP Associate (the SOCKS5 command for UDP).
• The target website has not advertised HTTP/3 support yet (unlikely for the test page).
