How to read a NS record check

NS records identify the authoritative nameservers for a DNS zone.

When to use this lookup

Use this lookup after a registrar nameserver change or when parent-zone delegation and the child zone appear inconsistent.

Example

example.com NS ns1.example.net
Answer shape
A set of authoritative nameserver hostnames for the queried zone.
Common failure
The parent delegation and child-zone NS set disagree, or required in-bailiwick glue is missing or stale.
Related checks
SOA record, A record, AAAA record

Troubleshooting checklist

  • Compare the registrar delegation with NS records inside the zone.
  • Verify glue records for in-bailiwick nameservers.
  • Allow for the parent delegation TTL before declaring propagation complete.
