We have a single subnet of 192.168.1.0 . with a subnet mask of 255.255.255.0
We are now running out addreses and want to increase the number of available addresses by changing the subnet mask to 255.255.252.0
What are the things i should consider before making the changes.
BTW, there some layer2 switches also in the network. Will these pose any problems after te changes?
There are no routers within the network
There is only one physical network spread over couple of offices interlinked by fiber
