How do you subnet a class B network?

Class B – Two Bit Subnetting If we include two bits from the host part to the network part, the subnet mask is changed into 255.255. 192.0. The two bits added to network part can have four possible values in third octet, 00, 01, 10, and 11. That means, we can get four networks if we do a two bit subnetting.
