What NS records do
They point a domain to the authoritative nameservers that control DNS responses.
Why TTL matters
Lower TTL means faster propagation of changes but may increase DNS query load.
Common use cases
Domain migration checks, registrar setup audits, and DNS troubleshooting.
Resolver source
Results come from Google Public DNS-over-HTTPS for reliable record querying.
Check authoritative nameservers for a domain using a single DNS API query and get a clean JSON output for troubleshooting and audits.
Only the domain you enter is sent to Google Public DNS for one NS query. No files or credentials are uploaded.
