DNS Lookup

Query DNS records (A, CNAME, MX, TXT, NS) for any domain in real-time.

About the DNS Lookup tool

The DNS Lookup tool queries a domain's DNS records in real time, returning A and AAAA addresses, CNAME aliases, MX mail servers, TXT records and NS name servers. Together these give you a clear picture of how a domain is configured across the record types that matter most for routing traffic and delivering email.

Developers, system administrators and site owners use it to verify that DNS changes have propagated, to debug email delivery by inspecting MX and TXT records such as SPF, and to confirm exactly where a domain currently points. Having the key record types presented in one view speeds up diagnosis when something is not resolving as expected.

Lookups are performed live and the results are shown in your browser without your queries being retained. With no install and no account, it is a fast and convenient first step whenever the behaviour of a domain needs investigating. That makes it equally handy for a one-off check or for confirming a migration across several domains.
