DNS Lookup

Look up DNS records for a hostname or domain. Only the requested record types are queried. Input is validated; only hostnames (letters, digits, hyphens, dots) are accepted.

Why use a DNS lookup tool?

A DNS lookup shows how a domain or hostname resolves: A and AAAA (IP addresses), MX records (mail servers), TXT (SPF, DKIM, verification strings), NS and CNAME. Essential for email setup, migrations, and debugging.

What each record type does

A and AAAA map a hostname to IPv4 and IPv6 addresses. MX records list the mail servers for the domain (with priority); receivers use them to deliver mail. TXT records hold arbitrary text — often SPF policies, DKIM public keys, or domain verification. NS records name the authoritative nameservers; CNAME points one name to another. SOA (Start of Authority) gives the primary nameserver, serial number, and refresh/retry/expire values used for zone transfers and caching.

Quick tips

  • Check MX records before changing mail providers; wrong MX means lost emails.
  • TXT records often hold SPF, DKIM keys, or domain verification; missing or wrong TXT can break deliverability.
  • Use SOA to see the primary nameserver and serial; useful when tracking DNS changes or propagation.

Things to consider

DNS is cached at many levels (browser, ISP, TTL). After changes, results may lag. Choose only the record types you need to keep queries fast and clear. Some hosts or CDNs return different results by location.
