I've got a client that changed the subnet mask of his class C network to 255.255.252.0. It was 255.255.255.0. The address range that we were using was 192.168.253.0 - 192.168.253.254. Now the client is trying to use the 192.168.252.0 - 192.168.255.254 range. This just does'nt look right to me.
Has anyone got any thoughts on it ?
