Class B IP address In Internet Protocol version 4 (IPv4), a unicast address in the range 128.0.0.1 to 191.255.255.254. Class B addresses are identified by a beginning set of 2 bits in a 10 sequence.The next 14 bits identify the specific network, with 16,384 (214) theoretically possible. As addresses 0 and 16,383 are reserved, 16,382 network addresses remain available for assignment. As the specific host on the network is identified in bits 16 through 31, as many as 65,634 (216 –2) hosts can be supported per network. See also binary notation, bit, host, IPv4, network, and unicast. |
