Answer 1

Answer: Three octets

Explanation: Class A addresses were intended to accommodate very large networks, so only the first octet is used to represent the network number. This leaves three octets, or 24 bits, to represent the host portion of the address. With 24 bits total, 224 combinations are possible, yielding 16,777,216 possible addresses.

Hope this helps!
