ABOUT

DNS resolvers are the servers on the Internet that translate domain names into IP addresses. You may wish to identify these servers to verify your network configuration or to check for dns leaks while using an anonymizing vpn service.

This web tool identifies your dns resolvers by attempting connections to randomly generated subdomains of our domain name in your browser. Our custom dns server receives the requests from your dns resolvers and uses the randomly generated part to link the requests to you.

DNSSEC is a mechanism by which dns responses can be authenticated. You may wish to verify proper DNSSEC usage to protect yourself against dns cache poisoning and similar attacks. This web tool attempts connections to domains which are purposely set up to fail DNSSEC authentication and warns you if one of those connections is successful.
