    13  NS adds a NS record to the domain. The name should be the relative label for the domain.
    14  
    15  The name may not be `@` (the bare domain), as that is controlled via [`NAMESERVER()`](NAMESERVER.md).
    16  The difference between `NS()` and [`NAMESERVER()`](NAMESERVER.md) is explained in the [`NAMESERVER()` description](NAMESERVER.md).
    17  
    18  
    19  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 `.`.
