DNS error

One or more of the nameservers listed at the parent servers are not listed

Hi all,

I get the following error on my site from DNS report:

ERROR: One or more of the nameservers listed at the parent servers are not listed as NS records at your nameservers. The problem NS records are:

ns1.example.com
ns2.example.com

What does this mean? How can it be fixed?

To resolve this, you probably need to have the zone file modified to replace NS entries by :

example.com. 3600 IN NS ns1.example.com.
example.com. 3600 IN NS ns2.example.com.

The ns1/ns2 entries should also have valid DNS themselves and point to actual nameservers.

Wait, what are zone files? :)
