We run out of IP addresses in a school environs which is part of a forest. Parent domain hadles exchange and root. To expand the IP scope we are going to use 10.100.20.0 using subnet mas of 255.255.252.0
Now we could not increase the ip as the IP address range has been used up. By other school in the the same forest so we have to create a new IP address for the server.
We are behind a sonic wall. should i worry about chnaging host records as well after changing the IP of th server
