DNS Compare

Query a list of records against multiple DNS servers side-by-side and highlight where they disagree. Great for verifying propagation, spotting split-horizon drift, or auditing resolvers. Records with no explicit type are probed across all common types.

IP or hostname, optional :port and a label after a space. Private/reserved IPs are blocked.
name alone probes every type. Add a type (A, TXT, MX…) to target one. JSON [{"name":"…","type":"A"}] also accepted.
Legend Identical — same values & TTL Minor — values match, TTL/SOA-timers differ Different — values disagree or present on some servers only No answer — server errored / unreachable
