NS Lookup
NS Record Lookup - Find Nameservers
Look up NS (Name Server) records to find authoritative DNS servers for any domain.
How It Works
The tool queries the NS records for the domain, which returns the list of authoritative nameservers. These servers hold the master DNS zone file for the domain.
Understanding Results
Results show all nameservers responsible for the domain. Most domains have at least 2 nameservers for redundancy. The nameservers listed should match what is configured at your domain registrar.
