DNS Records Lookup
See every common DNS record for a domain at once: A, AAAA, MX, NS, TXT, CNAME, SOA and CAA.
How it works
Useful for checking a change has propagated, finding which verification TXT records a domain publishes, or seeing which DNS host and mail provider it uses.
Automate it with the API
Run this check for every address in your product, from any language.

Frequently asked questions
Why don't I see my new record?
DNS answers are cached for the record's TTL. Wait for the previous TTL to expire and check again.
