Written on 13:37 by Ahmet Emir
The aboriginal 3 bytes of a Class C arrangement abode are committed to the arrangement allocation of the
address, with alone 1 beggarly byte actual for the bulge address. Here’s the format:
network.network.network.node
Using the archetype IP abode 192.168.100.102, the arrangement abode is 192.168.100 and
the bulge abode is 102.
In a Class C arrangement address, the aboriginal three bit positions are consistently the bifold 110. The
calculation is as follows: 3 bytes, or 24 bits, bare 3 aloof positions leaves 21 positions.
Hence, there are 221, or 2,097,152, accessible Class C networks.
Each different Class C arrangement has 1 byte to use for bulge addresses. This leads to 28 or 256,
minus the two aloof patterns of all 0s and all 1s, for a absolute of 254 bulge addresses for each
Class C network.
