Before I do so I'd like to confirm that changing the subnet mask of the network as defined on the router won't cause connectivity problems for connected hosts.
If it will cause connectivity problems, what is the correct way to go about this? Change the subnet mask on the hosts first, then change the subnet mask on the networking equipment?
