DNS lookup
Look up A, AAAA, MX, TXT, NS, and CNAME records for any domain.
Enter a domain to see its DNS records: A and AAAA (where it points), MX (mail servers), NS (nameservers), CNAME (aliases), and TXT (SPF, verification, and more). Useful when you're migrating hosts, debugging email, or confirming a DNS change has taken effect.
Frequently asked questions
Why don't my new records show up?
DNS changes take time to propagate as caches expire (TTL). If you just made a change, give it a few minutes to an hour and check again.
What's an MX record?
MX (mail exchange) records tell other servers where to deliver email for your domain. No MX record means mail bounces.
What's the difference between an A record and a CNAME?
An A record points a name directly at an IPv4 address (AAAA does the same for IPv6), while a CNAME aliases one name to another name. You can't put a CNAME at the apex (root) of a domain alongside other records.
What does the TTL value mean?
TTL (time to live) is how long resolvers may cache a record, in seconds. A 3600 TTL means caches hold the answer up to an hour; lower it before a planned change so updates propagate faster.
Why are TXT records often used for verification?
TXT records hold arbitrary text, so providers use them to prove domain ownership and to publish SPF, DKIM, and DMARC policies. Long values are split into multiple quoted strings that are joined back together.
How is this different from a DNS propagation check?
This tool shows the records as one resolver sees them right now; the DNS propagation checker queries several public resolvers at once so you can confirm a change has rolled out everywhere.
