Hey there,

I just broke down my class B dhcp server so that I have (/21) and I am wondering how to do the automatic update with reverses.

I suppose I can just have a 21.172.IN-ADDR.ARPA reverse and put EVERYTHING in it, but I really want to break it out.

If I create 0.21.172.IN-ADDR.ARPA reverse, will the DHCP server, and DNS server know that it is a /21 and put everything from 172.21.0.x thru in?

Just checking.
