Check DNS records for any domain.
See A, AAAA, CNAME, MX, NS, TXT, SOA, CAA and more — with TTLs, plus SPF, DMARC and DKIM checks and provider detection.
Every record type
A, AAAA, CNAME, MX, NS, TXT, SOA, CAA, SRV and PTR records in one report, with TTLs and priorities, queried live from public resolvers.
Email deliverability checks
Instantly see whether SPF, DMARC (and its policy) and DKIM are in place, so your mail lands in the inbox instead of the spam folder.
Provider detection
We recognise the DNS host behind the name servers and the email service behind the MX records — Cloudflare, Google Workspace, Microsoft 365 and more.

A DNS lookup asks the public resolvers for every record type published for a domain — A and AAAA (web server IPs), CNAME (aliases), MX (mail servers), NS (name servers), TXT (SPF, DKIM, DMARC and verification strings), SOA, CAA, SRV and PTR — and shows you exactly what the rest of the internet sees right now.
