![]() This means our host bits are the last 11 bits of the IP address, because we find the host mask by inverting the network mask: Host bit mask : 00000000 00000000 00000hhh hhhhhhhh The broadcast address converts all host bits to 1s. Align the bits in both addresses, and perform a logical AND on each pair of the respective bits. The network address is the logical AND of the respective bits in the binary representation of the IP address and network mask. ![]() the left-hand-side of the binary number). Then, count the number of contiguous 1 bits, starting at the most significant bit in the first octet (i.e. ![]() Calculating the Netmask Length (also called a prefix):Ĭonvert the dotted-decimal representation of the netmask to binary. ![]()
