How it works

1
We query public DNS over HTTPS (Cloudflare 1.1.1.1).
2
We read A / AAAA (addresses), CNAME (aliases), MX (mail), NS (nameservers), TXT (SPF, verification…), CAA (which CAs may issue certificates) and SOA (zone authority).
3
No registration, no rate-card — just the live answer from DNS.

FAQ

Is it free?

Yes — DNS lookups are free and need no signup.

Why are some records empty?

A domain simply may not have that record type (e.g. no AAAA / no MX / no CAA).

What is the CAA record for?

CAA lists which certificate authorities are allowed to issue TLS certs for the domain — an unexpected entry can signal misissuance risk.

Can you monitor DNS changes?

Yes — DNS change monitoring is live. Add the domain in @gmediatoolsbot and we alert you in Telegram when A/AAAA/MX/NS/TXT records change.
