WebRTC leak test

WebRTC can expose local and public addresses even behind a VPN. Modern browsers usually mask local IPs as random .local names.

DNS leak test

Your browser resolves a random one-time name that only this site's DNS server can answer, revealing which resolver actually handles your lookups. Behind a VPN, answers arriving from your ISP's resolver are a DNS leak. Only the resolver's address — and, if it forwards one, your network prefix rounded to /24 (IPv6: /48) — is kept, for ten minutes.
