How to Verify Proxy Anonymity: IP, DNS and WebRTC Leaks

Step 1 — basic IP check

Simplest check: open 2ip.com or whatismyipaddress.com. It should show the proxy IP, not your real one. If your home IP is visible — the proxy isn't working.

Step 2 — proxy transparency

HTTP proxies sometimes pass your real IP in headers like X-Forwarded-For or Via. Such a proxy is called transparent and provides no anonymity.

Check: browserleaks.com/proxy shows every header the site sees. If there's no X-Forwarded-For with your real IP — the proxy is anonymous. Good SOCKS5 proxies don't pass these headers at all.

Step 3 — DNS leaks

Even if HTTP traffic goes through the proxy, your browser/OS may resolve DNS via your ISP. The site won't see your IP, but DNS queries reveal you're from Russia/Ukraine/wherever.

Check: dnsleaktest.com, press Extended test. DNS servers should be in the same country as the proxy. If your ISP's servers show up — you have a leak.

Fix: anti-detect browsers have a "DNS over proxy" toggle (mandatory for multi-accounting). Regular browsers: enable at the OS proxy level.

Step 4 — WebRTC leak

WebRTC is the P2P calling protocol built into all modern browsers. It can query your real IP around the proxy to establish direct connections.

Check: browserleaks.com/webrtc. If your home IP shows up — you have a leak. Critical for multi-accounting.

Fix:

• Chrome/Edge: WebRTC Leak Prevent extension
• Firefox: about:config → media.peerconnection.enabled → false
• Anti-detect: disable WebRTC in profile settings

Step 5 — ban-score check

Not every hidden IP is "clean". An IP can be anonymous to a site yet flagged as a proxy in anti-fraud databases (IPQualityScore, Scamalytics, IPInfo).

Check: ipqualityscore.com/free-ip-lookup-proxy-vpn-test or scamalytics.com. Both show:

• Fraud score — 0-100, lower is better
• Is Proxy — whether the IP is flagged as a proxy
• Is Bot — whether it's been spotted in bot activity

For Instagram/TikTok/banks you need score < 25 and "Not detected as proxy". For scraping and SEO — up to 50 is fine.

Checklist

• [ ] 2ip.com shows proxy IP, not yours
• [ ] browserleaks.com/proxy — no X-Forwarded-For with your IP
• [ ] dnsleaktest.com — DNS in the proxy's country
• [ ] browserleaks.com/webrtc — no home IP visible
• [ ] ipqualityscore.com — fraud score in the acceptable range

All five green — the proxy is set up correctly.

Why it matters

A single WebRTC leak = all your accounts linked to your real IP. The platform sees the link and bans the whole cluster at once. Verification takes 5 minutes and saves dozens of hours of account recovery.
