How Accurate Is a Proxy Check for Detecting Hidden IPs? or Can a Proxy Check Really Tell If My IP Is

Honestly, proxy checks are kinda basic. They mostly rely on databases of known VPN/proxy IPs.

If your VPN isn’t in their list, it’ll slip through. Some tools like WhatIsMyIPAddress or DNSLeakTest can help spot leaks, but they’re not foolproof.

The difference between VPN and proxy? Most checks don’t care—they just see "not a residential IP" and flag it.

For better accuracy, you’d need something like FingerprintJS, but that’s overkill for casual use.
