Using a different domain name as the DNS server for a domain

[Chris Buxton]

You can create the NS record as you have described (type = NS, not A), but remember to put a dot on the end:

birimgrup.com.  in  NS  ns1.optiplex-networks.com.

This is quite common. Here are some real-world examples:

com.			IN	NS	a.gtld-servers.net.

menandmice.com.		IN	NS	ns0.c.is.

As for reverse records, these are indexed by the IP address, not be the domain name on the right hand side. Your PTR records will go in the reverse zone you already have.
