What is the address range of a Class B network address in binary?

A Class B network address in binary begins with the bit pattern 10xxxxxx. This indicates that the first two bits of the address are set to '10', which defines the Class B range in the IPv4 addressing scheme. The remaining bits (represented by 'xxxxxx') can be any combination of 0s and 1s, allowing for a significant number of host addresses within a Class B network.

Class B addresses range from 128.0.0.0 to 191.255.255.255 in decimal notation, which reflects that the first octet must be between 128 and 191. This range is crucial for subnetting and classful networking, as it identifies the network portion and leaves enough bits for host addresses.

Understanding this format helps in recognizing how addresses are allocated and classified, which is essential for network design and management.
