Understanding Your NS Lookup Results
NS records show which nameservers control DNS for a domain. This is one of the first checks when a domain is not resolving correctly.
PROVIDER
DNS Provider Context
Use the listed nameservers to confirm whether the domain points to the expected DNS provider.
MISCONFIGURED
Missing or Mismatched NS
Wrong nameservers can break DNS records, email routing, website access, and verification flows.
About This Tool
The NS Lookup Tool checks the nameserver records for a domain. Nameservers indicate which DNS servers are authoritative for that domain's public DNS records.
Use this tool during domain setup, DNS provider changes, hosting migrations, and troubleshooting when records are not updating as expected.
Why It Matters
1
Confirm DNS provider
See which nameservers currently control the domain's DNS zone.
2
Troubleshoot stale records
If DNS edits are not showing, the domain may still point to old nameservers.
3
Support migrations
Validate registrar-level nameserver changes before switching traffic.
4
Improve audit confidence
Document authoritative DNS ownership during technical SEO or IT reviews.
How To Improve
1
Check current nameservers
Enter the domain and review the listed NS records.
2
Compare registrar settings
Make sure the registrar points to the same nameservers as your DNS provider expects.
3
Avoid mixed providers
Do not edit records in a DNS dashboard that is not authoritative for the domain.
4
Wait and recheck
Nameserver changes can take time, so verify again after propagation.
