Our organization has outgrown our class C IP addressing scheme. We plan to change to a class B address range, to accommodate all of our computers. Currently we have 5 buildings – fiber ran between them – 3com switches in all buildings and Ethernet throughout from there to the desktops. Our internet connection comes from a local ISP where we have a cable modem and an old cisco router which gives us our connection to the outside world. Our network is setup as DHCP to give our machines their IP addresses. Both DHCP servers are running Windows NT 4.0. We are looking to try and change over our IP addressing with a minimal amount of downtime. Is there a way to use two different IP classes at the same time, while we go building to building changing the IP’s of the printers, servers, and other devices??? Any help would be greatly appreciated.
