Yeah, its 5am - got clients that rely on me to get things done…

DNS: Best free tool to use: http://www.dns.lu/en/EN-LUTestNoms.php

If seeing “not advertising as nameserver”, that means in the zone file that server is not listed:

mochabomb.com.  IN      NS ns1.mochabomb.com.
mochabomb.com.  IN      NS ns2.mochabomb.com.
mochabomb.com.  IN      NS ns4.mochabomb.com.

.. for the server it resides on - and that record can be a slave record, just need to add all slaves in the master DNS server so that the slave server advertizes itself as an authority….

In /etc/named.conf is where a zone is set as master or slave. A slave can be authoritative if its name is listed/resolved by the master record.
