How this tool works?

This tool will query the availability of a domain across the more prominent DNS resolvers in the market. It will report if a domain is resolving, to what IP it is resolving, and if a domain is blocked by a specific DNS resolver. This tool is good to gauge if a domains resolution issues are isolated to a specific resolver, or global.


We will test your domain name against 17 of the most popular public DNS resolvers available.
