DNS LOOKUP

DNS lookup

Look up a domain’s A, AAAA, MX, TXT and other DNS records. Live queries through Cloudflare 1.1.1.1.

Back to home

Enter a domain name without a URL. Example: astrotor.com

Enter a domain name to explore its records.

Queries are sent to Cloudflare 1.1.1.1. Results reflect its resolver cache; this does not measure propagation across all providers or test DNS leaks. Astrotor does not store lookup history.

GOOD TO KNOW

A few clear answers.

Let’s make the technical terms a little simpler.

What does TTL mean?

TTL is the record’s remaining time in the resolver cache, in seconds. It normally decreases between lookups.

Does a missing record mean the domain is broken?

No. Not every domain uses every record type. An empty answer and NXDOMAIN (domain not found) are different results.
