Records and types

When to use it

  • You need the current A/AAAA, MX, TXT, CNAME, NS, CAA, or other record for a host.
  • You want to confirm what a specific public resolver is serving at this moment.

  2. Choose a resolverCloudflare answers by default. Switch to Google, AdGuard, DNS.SB, or OpenDNS to compare what another operator is serving.

Operational notes

Keep in mind

  • TTL is the resolver’s remaining cache lifetime, not the zone’s configured TTL.
  • Add mode=client to resolve directly from your browser via DoH, or mode=both to compare your network’s view against the server’s.
