Look up DNS records for any domain — A, AAAA, MX, TXT, NS, and CNAME — and see the values and TTLs in a clean table. Queries run over encrypted DNS-over-HTTPS to a live resolver, so you get current authoritative data.
How to look up DNS records
- Enter a domain or hostname (e.g.
example.com). - Pick the record type you want to see.
- Press Look up — the answers, their TTLs, and the query status appear below.
What each record type is for
A / AAAA map the name to an IPv4 / IPv6 address — the “where does this site live” record.
MX routes email, with a priority number before each mail host. TXT carries SPF, DKIM,
and verification strings — the plumbing behind email deliverability and domain ownership
proofs. NS names the authoritative servers for the zone. CNAME aliases one hostname to
another (common for www and CDN setups). Checking the right one is how you diagnose a site
that won’t resolve, email that won’t deliver, or a domain-verification step that won’t pass.
Reading TTL and propagation
Every record carries a TTL — the seconds resolvers may cache it. It’s the single most useful number when you change DNS: lower the TTL a day before a planned change and the switch propagates in minutes instead of hours. This tool queries a live resolver on each lookup, so it reflects authoritative data promptly — but remember other networks keep serving cached answers until their own TTL expires, which is why “it works for me but not for them” happens during a migration.
Private by design
The lookup runs server-side over encrypted DNS-over-HTTPS; we don’t store the domains you check. Pair it with the WHOIS lookup for registration details and what is my IP for your own address.
