Compare DNS answers from public resolvers

Check A, AAAA, CNAME, MX, NS, TXT, SOA or CAA records across selected DNS providers. Compare answer sets, an expected value, TTL and response times; export the report.

Your hostname is sent to our server, which queries the selected public resolvers. Anycast providers are reached from this server, not from independent countries worldwide.

Choose DNS resolvers (6)

Different answers may reflect cache state, location-based DNS or filtering. Equal answers do not prove global propagation. TTL is a remaining cache lifetime, not a countdown until every resolver updates. Expected-value matching is exact for one answer; TXT is case-sensitive.
