Hi all. Easy question hopefully.. I currently have about 250 reverse zones, mostly class Cs. I did some analysis and found that this still doesn't include all the Cs covered by our DHCP scopes. Instead of adding additional class C zones, I'd like to create two class Bs to cover the ranges being passed out by DHCP. My question is whether this will have an effect on the existing class Cs, or in other words, will the more "specific" reverse zones get priority for queries and dynamic updates, or will I need to create delegations to the other zones? Long-term, I'd like to collapse all the Cs into the two Bs.
For example, suppose we have:
10.20.30.in-addr.arpa
12.20.30.in-addr.arpa
What happens if I create 20.30.in-addr.arpa? If you can reference any documentation I'd appreciate it.
Thanks!
Paul
