DNS Records

DNS Records brings together 10 free tools with no sign-up to inspect the data published by a domain. DNS Lookup A and AAAA show IPv4 and IPv6 addresses, MX DNS Lookup examines email, and DNS TXT Lookup displays text records. Other entries cover NS, SOA, CNAME, CAA, SRV and NAPTR. These checks help webmasters, administrators and email teams verify a configuration.

Start with the type of information you need. To reach a site, A and AAAA are the first reflexes. For email, look at MX. TXT records are often used to publish verification or policy information. NS and SOA describe DNS authority, CNAME follows an alias, CAA limits certificate authorities, SRV locates services and NAPTR handles rewrite rules. Use the tool that matches the record you need to validate.

How to use

  1. To reach a site, start with DNS Lookup A and AAAA DNS lookup to see published IPv4 and IPv6 addresses.
  2. For email, inspect MX DNS Lookup, then DNS TXT Lookup for verification or policy information.
  3. For authority, use NS DNS lookup and SOA DNS lookup, then follow an alias with DNS CNAME lookup.
  4. Complete as needed: CAA DNS Lookup for certificates, SRV DNS lookup for services and NAPTR DNS Lookup for rewrite rules.

Frequently asked questions

Which DNS record should I check first?

It depends on your goal. For a website, start with DNS Lookup A and AAAA. For email, MX DNS Lookup is the priority. If you are validating authority or delegation, turn to NS DNS lookup or SOA DNS lookup.

Can I look up a CNAME record?

Yes, DNS CNAME lookup follows the canonical alias of a name. It is useful for understanding which target a name points to. The tool is free, requires no sign-up and runs directly in the browser.

How do I check a DNS delegation?

Start with NS DNS lookup to identify the authoritative authorities, then SOA DNS lookup to read authority and serial. These two readings help see whether the delegation is consistent before examining A, AAAA or MX.

When should I use SRV DNS lookup or NAPTR DNS Lookup?

SRV DNS lookup helps find services and ports published in DNS. NAPTR DNS Lookup concerns rewrite rules. Both complement more classic records such as A, MX or CNAME.
