Prevent dynamic dns registration of 'localhost'

Hello

I work in a Heterogeneous environment, with both windows and unix systems

DNS is AD integrated and Dynamic DNS is handled via our DHCP servers (windows based)

Issue is this

Some test users are firing up exsi templates and joining them to the network / domain before configuring them. This results in the 'localhost' being dynamically registered in DNS

localhost 192.168.1.1 for example

This upsets our friends in the unix world to no avail.

As such - is there a way to 'prevent' dynamic registration for localhost?
