Free Tools / DNS & IP Lookup

DNS & IP Lookup

Look up the DNS records for any domain: addresses, mail servers, name servers, and text records. Enter an IP address instead for a reverse (PTR) lookup. Handy for debugging email, migrations, and propagation.

Resolved over DNS-over-HTTPS. Public records only. Rate limited to keep things friendly.

Record types

A / AAAA the IPv4 / IPv6 addresses a name points to.
MX mail servers that accept email for the domain.
NS the authoritative name servers.
TXT free-form text, often SPF, DKIM, and domain verification.
CNAME / SOA aliases and the zone's start-of-authority.
