# NS

NS adds a NS record to the domain. The name should be the relative label for the domain.

The name may not be `@` (the bare domain), as that is controlled via [`NAMESERVER()`](https://docs.dnscontrol.org/~/revisions/T4Wre387kGCjR4Bh4mfN/language-reference/domain-modifiers/nameserver). The difference between `NS()` and [`NAMESERVER()`](https://docs.dnscontrol.org/~/revisions/T4Wre387kGCjR4Bh4mfN/language-reference/domain-modifiers/nameserver) is explained in the [`NAMESERVER()` description](https://docs.dnscontrol.org/~/revisions/T4Wre387kGCjR4Bh4mfN/language-reference/domain-modifiers/nameserver).

Target should be a string representing the NS target. If it is a single label we will assume it is a relative name on the current domain. If it contains *any* dots, it should be a fully qualified domain name, ending with a `.`.

```javascript
D("example.com", REG_MY_PROVIDER, DnsProvider(DSP_MY_PROVIDER),
  NS("foo", "ns1.example2.com."), // Delegate ".foo.example.com" zone to another server.
  NS("foo", "ns2.example2.com."), // Delegate ".foo.example.com" zone to another server.
  A("ns1.example2.com", "10.10.10.10"), // Glue records
  A("ns2.example2.com", "10.10.10.20"), // Glue records
);
