DNS lookup

See every DNS record of a domain: A, AAAA, CNAME, NS, MX, TXT, SOA and CAA, as our resolver sees them right now.

Example: tusitio.pe or https://www.tusitio.pe. Takes a few seconds.

What we check

  • A and AAAA records (where the site lives)
  • NS records (who answers for the domain)
  • MX and TXT records (email and verifications)
  • SOA and CAA records

Frequently asked questions

I changed my DNS and nothing happens. Why?

Every record has a time to live (TTL). Until it expires, resolvers around the world keep serving the old value. Typical waits go from minutes to 48 hours.

What is the difference between A and CNAME?

An A record points a name to an IP address. A CNAME points a name to another name, which is then resolved again.

Why does the tool show no MX records?

The domain has no mail servers declared, so it cannot receive email. If that is not intended, add the MX records your mail provider gives you.
