WebRTC leak test
WebRTC lets websites ask your browser for its network addresses. With a VPN, a leak exposes your real IP.

DNS leak test
CheckingYour browser looks up a few random test names. Our DNS server records which DNS servers (resolvers) asked for them.

Test names and resolver IPs are deleted after 10 minutes.

Frequently asked questions
›What is an IP leak?
An IP leak happens when a website can see your real IP address even though you are using a VPN or proxy. Common causes are WebRTC, DNS requests that bypass the tunnel, and IPv6 traffic that is not routed through the VPN.
›What is a WebRTC leak?
WebRTC is a browser feature for real-time calls. To connect peers it can reveal your network addresses to any website, including your real public IP behind a VPN. This page asks public STUN servers what address they see and compares it with the IP websites see.
›What does the IP risk score mean?
It is a simple, transparent score from 0 to 100. Tor, VPN, proxy and data center networks add points because anti-fraud systems often challenge those IPs. A high score doesn't mean you did anything wrong; it means some sites may show extra CAPTCHAs or block you.
›Is a VPN IP bad?
Not necessarily. VPN IPs are shared by many people, so some sites treat them with caution. If you use a VPN on purpose, “VPN detected” just confirms it is working.
›Do you store my IP address?
No. Your IP is used to answer the request and to look up its public network information. Results are not saved to a database.
›Why can't you tell residential from business IPs?
That needs a commercial IP database. This free version uses open signals (network name, ASN, reverse DNS) and labels its confidence honestly.
