Look up a domain's name servers.
See exactly who's authoritative for its DNS.
Enter a domain name below to see the name servers it's delegated to, straight from the registry — plus the SOA record for the zone.
A name server lookup shows which servers are authoritative for a domain's DNS — who controls where its website and email point. It pulls the NS records and SOA straight from the registry. The fast way to confirm a delegation or migration has propagated. Free and instant, no login or rate limits.
What a name server lookup actually tells you.
Who's authoritative
A domain's NS records name the servers that hold the master copy of its DNS zone. Whoever controls those servers controls where the domain's website, email and subdomains resolve.
Confirming propagation
After changing a domain's nameservers at the registrar, propagation can take anywhere from minutes to 48 hours. Running a lookup confirms which set is currently live.
SOA & zone serial
The SOA record names the primary name server for the zone and its serial number, which increments on every DNS change — useful for confirming a recent edit actually saved.
