Reading the answer

  • The NS records name the servers that hold the domain's DNS. Whoever runs them is the place to edit records.
  • There are usually two to four, so the domain keeps working if one is unreachable.
  • The nameservers are set at your registrar. Changing them moves your DNS to a new host, so copy your records over first.

Every field and accepted value: the NS record explained. Other lookups: MX lookup, TXT record lookup, CNAME lookup, A record lookup.

Frequently asked questions

How do I find out who hosts my DNS?

Look up the NS records. The nameserver names usually say which provider they belong to, such as Cloudflare or your registrar.

How long does a nameserver change take?

Often an hour or two, but up to two days: the NS records at the registry have their own long TTL.

Is the DNS host the same as the registrar?

Not necessarily. The registrar is where you rent the name; the DNS host is whoever the NS records point at.
