zone has no NS records

  • 772

I have a bind zone with an entry:

ns  NS              localhost.

this gives the error: "zone has no NS records"

changing it to the following solves the error. 

@   NS              localhost.

Can somebody explain why the first option isn't a valid NS record?

domain-name-system

  1. If your input file includes something like this:

    $ORIGIN example.com.

    Then:

    @ NS localhost.

    Is equivalent to:

    example.com. ns localhost.

    Whereas:

    ns NS localhost.

    Is equivalent to:

    ns.example.com. NS localhost.

    In the first example, using @, you are specifying an NS record for the domain example.com. In the second example, you are specifying an NS record for the domain ns.example.com. So you're getting that error because the domain you've told BIND about -- example.com -- does not have any nameserver records.
