DNS Lookup
Query any DNS record type - A, AAAA, MX, TXT, NS, SOA, CAA, SRV, DNSKEY and more - straight from your browser over DNS-over-HTTPS.
Result
What the answer will show
- Status
- the DNS response code - NOERROR, NXDOMAIN or SERVFAIL
- Answer section
- each record with its remaining cache TTL
- DNSSEC
- whether the resolver validated the chain of trust
- Zone file form
- the same records ready to paste into a zone
About DNS Lookup
This is a browser-native replacement for dig. The query is sent as DNS-over-HTTPS from your machine directly to the resolver you pick, so the answer reflects what that resolver sees - including its cache - rather than what a server in some other country sees.
Reading the result
The status field is the DNS response code. NOERROR with zero answers is NODATA: the name exists but has no record of that type - a completely different condition from NXDOMAIN, where the name does not exist at all. SERVFAIL usually means a broken delegation or a DNSSEC validation failure, not a missing record.
The TTL is what remains of the cache lifetime at that resolver, so it counts down on repeat queries rather than showing the value configured in the zone.
DNSSEC
The AD (Authenticated Data) flag means the resolver validated the chain of trust for this answer. Its absence does not prove tampering - most zones are still unsigned - but for a signed zone, losing AD is a red flag worth chasing.
Common use cases
- Confirming an A or AAAA change has actually taken effect at a public resolver.
- Checking MX and TXT records while debugging mail delivery.
- Reading CAA policy before requesting a certificate from a new CA.
- Finding the authoritative nameservers for a domain during a delegation problem.
Edge cases and gotchas
- ANY queries are refused or truncated by most modern resolvers (RFC 8482) - query the specific type instead.
- Answers come from a public resolver cache, so they may lag behind an authoritative change by up to the record TTL.
- Split-horizon or internal-only names will not resolve here; this sees the public view only.
