About DNS Lookup

DNS lookup shows which addresses and records a hostname resolves to—useful for mail and migration checks. toco.tools performs resolution on the server because browsers cannot issue arbitrary DNS queries. Results reflect the resolver answer at query time.

How to use

  1. Enter a hostname
  2. Run the lookup
  3. Review each record type

FAQ
