🧭 NS Record Checker
List the authoritative name servers responsible for a domain's DNS zone and confirm delegation.
NS Record Checker
List the authoritative nameservers delegated for a domain to ensure DNS is pointed at the right provider.
What you'll see
- Nameserver hostnames returned by the resolver in the order they are published.
- TTL information so you know how long registries and resolvers will cache delegation data.
- Glue records or additional IP addresses when they are supplied by the resolver.
Common use cases
- Verify registrar updates completed after switching DNS providers.
- Audit that every domain in a portfolio uses the expected managed DNS platform.
- Check secondary nameserver coverage before planning maintenance windows.

List the authoritative name servers for a domain and confirm DNS delegation is correct.
Prepared query:
example.comTroubleshooting tips
- Changes to NS records can take many hours to propagate—plan cutovers around TTL values.
- Maintain at least two nameservers on separate networks for resiliency.
- If responses differ from your registrar's portal, double-check the parent zone delegation.
FAQ
- Why do I see nameservers I don't recognize?
- Registries cache delegations. If you recently migrated providers, cached NS records may still appear until TTLs expire.
- Does this show glue records?
- Yes. When the resolver returns A or AAAA glue for the nameserver hostnames, they are listed in the Additional section.
- How many NS records should I have?
- Most TLD policies require at least two distinct nameservers. More can improve redundancy but watch for stale hosts.
