(also Class B IP)
Class B IP address is an IP address used for networks that are medium to large in size. Class B makes it possible to have 16,384 networks because the network ID is made up of the first two octets. IP addresses of class B have the value 10 assigned to their higher-order bits in the first octet of their addresses at all times. The network ID is determined using the remaining 14 bits of the address. The host in any given network can be identified by using the first 16 bits of the host ID. There is room for about 65,000 hosts on a network due to the host ID. The values of Class B network numbers start at 128 and end at 191.
