Anonymous Proxy Checker

Anonymous Proxy Checker

Check whether an IP is an anonymous proxy concealing its user’s real address. See the proxy type and a confidence score in seconds.

Overview

What is an anonymous proxy?

An anonymous proxy hides the real IP address of the person behind it, so the destination server only sees the proxy. “Elite” or high-anonymity proxies go further and strip the headers that would reveal a proxy is in use at all. An anonymous proxy checker tests an IP for these behaviours and tells you whether the address is concealing its true origin, so you can decide how much to trust the request.

Signals

How the anonymous proxy check works

Anonymity levels differ, so we look for both obvious and hidden proxies.

Header inspection

Missing or forged forwarding headers that signal high-anonymity proxies.

Open proxy tests

Detection of reachable anonymous proxy endpoints.

Pool & reputation

Membership in proxy pools and prior anonymising behaviour.

Tor & relays

Correlation with Tor exit nodes and known relays.

ASN context

Hosting vs. residential ownership of the IP.

Confidence score

A 0–100 score reflecting how certain the proxy verdict is.

Use cases

Where teams use it

Fraud screening

Forum & marketplace trust

Reduce abuse from users hiding behind proxies.

Access control

Restrict sensitive actions from anonymising IPs.

Investigations

FAQ

Frequently asked questions

It means the IP is relaying traffic in a way that hides the user’s real address — either by acting as a proxy or by stripping headers that would reveal one. Our checker labels the type and gives a confidence score.
