NS-record

Q: Wat is een NS-record?

Lists the authoritative name servers for a zone. NS records tell the DNS system which servers are responsible for a given domain. They appear at the apex of a zone and are also delegated from the parent zone (the TLD operator). Recursive resolvers use NS to find which IPs to ask for further records.

Voorbeeld zone-file-entry

Gangbare use cases

▸Change DNS providers — update the NS records at the registrar.
▸Delegate a subdomain to a different DNS provider.
▸Split-horizon / private DNS by changing internal NS targets.
▸Diagnose propagation: query NS records via different resolvers (1.1.1.1, 8.8.8.8, 9.9.9.9) to see who has the new set.

Veelvoorkomende valkuilen

The NS set at the parent zone must match the apex NS set inside the child zone. Mismatches ("lame delegation") cause intermittent failures hard to debug.
