At our company right now, we are using the 192.168.1.x/24 for our network. We are going to bring in Voip, and want to expand from 254 to a little over 1,000 addresses. How is the best way to do this. I did see that I can change the subnet mask to 255.255.252.0. or 255.255.248.0. Would I then need to change the ip address from 192.168.1.x to something else?
