How to perform a DNS lookup

Resolve a domain to its A, AAAA, MX, TXT, or other records — step by step.

A DNS lookup answers a single question: what address (or other record) is associated with this hostname?

Steps

  1. Open the DNS Lookup tool.
  2. Enter the hostname (for example, example.com).
  3. Pick the record types you want — A for IPv4, AAAA for IPv6, MX for mail exchangers, TXT for verification records.
  4. Run the query. You'll see the answers, their TTLs, and the time the lookup took.

Common gotchas

  • A new record won't appear immediately if the resolver has cached the old answer.
  • Some hosts return different answers depending on the resolver (CDN geo-routing).
