I have got the a small project, I joined a new company a week ago and realise they are running out of address space.
They are running 192.9.100.* addresses on a 255.255.255.0 subnet. I have recalculated the subnet range the be 220.127.116.11/23.
I need to implement this with minimum down time. I will not be changing the addresses of the routers, switches or Domain controllers. DHCP is running on the network with some static addresses.
Do I just need to set the new dhcp scope on a new server, then reconfigure the current one? How will I address the routers?
