WebRTC and DNS leak tests
Our own STUN and DNS servers see which address your UDP traffic and your DNS lookups really come from, and compare it with the IP sites see.
IP Checker
Your public IP, where the internet thinks you are, and a risk score from 40+ checks: WebRTC and DNS leaks, TCP/IP fingerprint, IP reputation and how consistent your browser or antidetect profile looks.

Look up another IP
Location, network type, Tor, VPN and blocklists for any public IPv4 or IPv6 address.
IP data: DB-IP (CC BY 4.0), PeeringDB, Tor Project, FireHOL, IPsum, X4BNet. Nothing you check here is stored.
IP reputation
Network type from the ASN: residential ISP, mobile carrier or a hosting network. Plus Tor exits, VPN ranges, public blocklists and “fake ISP” ranges.
Antidetect profile check
User-Agent and Client Hints in JavaScript and HTTP, the real engine version, screen, fonts, GPU, voices, canvas and audio noise, Web Worker values: what profiles most often get wrong.
What this page checks
Your public IP is the address the websites you visit actually see. With a proxy it belongs to the proxy, and everything else on this page tells you whether the rest of your setup agrees with it: the time zone the browser reports, the language it asks for, the DNS resolver that answers for you, the address WebRTC exposes and the operating system your TCP connection announces.
A mismatch in any of these is what anti-fraud systems look for. A US residential IP with a Moscow time zone and a Russian default language is a classic giveaway, and so is a Windows browser whose TCP handshake comes from a Linux server. The risk score adds up every mismatch the way a strict anti-fraud system would. Antidetect browsers fix the browser side; the proxy decides the network side.
Questions about IP checks
Every check ends as passed or as an issue with a severity: critical adds 35 points, high 20, medium 10, low 4 and a note 1. The score is the sum, capped at 100, and lower is better: 0–33 is low risk, 34–66 medium, 67 and above high. Open "View all checks" to see each issue and what triggered it.
Yes: open this page inside the profile with its proxy on. The checker compares what the profile claims (User-Agent, Client Hints, platform, time zone, language, screen, GPU, fonts, speech voices) with what the browser engine, the HTTP request and the network really show, the way anti-fraud systems do, and explains every mismatch it finds.
Geolocation databases map IP ranges to the ISP's registered location, which can be a nearby city. Country-level accuracy is high; city-level is approximate.
No, the proxy works. WebRTC sends UDP around it inside the browser, so any page can read the address behind the proxy. Disable WebRTC, or use an antidetect browser that routes it through a proxy with UDP support.
The first packet of every TCP connection carries traits of the operating system that sent it: initial TTL, window size and option order. With a proxy or VPN server in between, that packet comes from the server, so a Windows browser can show up as Linux. Anti-fraud systems compare the two.
Your browser looks up a few random names that only our own DNS server can answer. Whichever resolver asks for them is the one resolving names for you, and its country and network show whether DNS goes the same way as your traffic.
No. The checks run in memory and the report is only shown to you; the DNS test names are kept for five minutes to match the lookups and are not tied to an account. Use "Download report" to keep a copy.
