A record of domain name must be name server ?

Well this is a confusing point but it's rather an administrative 
decision to make.
If indeed the network\server\domain administrator is not aware of his 
services he will either have or will not have decision to make.
It will depend on whether he knows what he is doing.
Mish-mosh or banana he will eat it one way or another.

One conclusion he will probably learn is that dns records takes from 24 
to about 48 hours to be forgotten from dns caches :D
