Hey...
Quick question.. Doing a lab which is saying that Router 1 has a S0/0/0 interface with an IP address of 10.1.1.1 and a subnet mask of 255.255.255.0
My question is... How is that possible? I know 10.0.0.0 is a private network, however it is still a class A network and should have a S/N Mask of 255.0.0.0
I am definately missing something!

VLSM explains how you take a network and subnet it without using a classful mask like the 255.0.0.0 you were expecting to see there. VLSM works with classless mask.. which can enable a subnet to have a ton more hosts if done properly.Goals for 2015: CCNP
