Subnetting— Determine the classes – Classful vs Classless Class A: The first bit in the first octet must remain a 0. The remaining seven bits can be a 1‚ giving a maximum total of 127. The first octet‚ however‚ cannot be 0 (local identification‚ or “this network”) or 127 (loopback). Class A first octet range is 0 through 127‚ although the valid range is 1 through 126. Class B: The first bit in the first octet becomes a 1. The second bit‚ however‚ must remain a 0. The remaining six bits can be a 1
