We are getting out of IP adresses in our DHCP Scope. Firstly we tought about changing the subnet mask to 255.255.252.0 (192.168.0.1/22) in order to get 1024 Ip adreses. the thing is that people are telling me that it should be better to change IP range to B Class (172.16.x.x).
We have a domain with one DC and an Exchange 2003 Server. What should be thre procedure to change IP range without having any DNs problems or other.
