I am implimenting VPN on a client network with LAN subnet on the reserved IP block 10.xxx.xxx.xxx
Since this is a Class A IP block..I would assume the subnet to be 255.0.0.0. But they are using 255.255.255.0
Is this a right thing to do ? Though their network is functioning properly as of now, will it create issues later on for Internetworking or VPN connectivity with other networks?
Pls refer if you a link to any authentic docs on this (Like RFC)
