Our current network is beginning to run out of IP addresses. We use 10.0.0.1 to 10.0.0.254 with a subnet mask of 255.255.255.0. I would like to change to subnet mask to 255.255.252.0 and came across the following link to do this without having to do a lot of manual changes (http://www.windowstricks.in/2009/06/how-to-change-subnet-mask-of-dhcp-scope.html
) on the DHCP server (Windows Server2008). I am assuming that after I make the change on the DHCP server, I will need to manually change the subnet masks on any devices that have static IPs. What would be the best order to make those chnages? Servers, then switches/routers, then printers, etc. Should I first change the devices and then make the change in DHCP? Thank you.
