DNS leak test
Find out which DNS servers your connection really uses. With a proxy or VPN on, they should match the proxy's country, not your ISP.
How to read the result
- With a proxy or VPN on, the servers listed should belong to the proxy provider or a public DNS service, not your home or office Internet provider.
- If your provider's name shows up (for example a home or corporate network), DNS lookups are leaving through your own connection: that's a DNS leak.
- To fix it: use SOCKS5 with remote DNS (socks5h, or your software's “DNS through proxy” option) or an HTTP proxy, which resolves names on the proxy side.
How the test works
Your browser tries to reach a few unique addresses under one of our domains. To find them it has to ask a DNS server, which in turn asks ours: that's how we see who made the request. The addresses detected are deleted after a few minutes.
