DNS Lookup
Query the public DNS records for any domain — A, AAAA, MX, TXT, NS and more — straight from your browser.
A DNS lookup resolves a domain name into the records that make the internet work: the A/AAAA records that point a name at an IPv4/IPv6 address, the MX records that route its email, the TXT records that carry SPF/DKIM/verification data, and the NS records that delegate authority.
Enter a domain above and this tool queries live DNS and returns every record type it finds. It is handy for debugging propagation after a change, confirming mail routing, or checking which nameservers a domain uses.
Frequently asked questions
Why do my new DNS records not show up yet?
DNS changes propagate gradually as caches expire. A record's TTL (time to live) controls how long resolvers cache it — until that expires you may still see the old value.
What is the difference between A and AAAA records?
An A record maps a hostname to an IPv4 address; an AAAA record maps it to an IPv6 address. A domain can have both.
Can I check MX (mail) records here?
Yes — the lookup returns MX records alongside the others, so you can confirm where a domain's email is routed.
