NS record
Names the authoritative nameservers for a zone. Everything else depends on these being right.
What one looks like
example.com. 86400 IN NS ns1.provider.com.
Things worth knowing
- The NS records at your registrar (the delegation) and the ones inside your zone should match.
- Delegation changes are cached by the registry and often take longer than ordinary record changes.
- Always run at least two nameservers, ideally on separate networks.
