Which IPv4 address class contains a total of 2,097,152 networks?

Class C IPv4 addresses allow for a maximum of 2,097,152 individual networks. This is due to the structure of the Class C addressing scheme, which designates the first three octets (the first 24 bits) for the network part of the address, while the remaining octet is used for host addresses.

In Class C, the first three bits of the address are always set to "110", which leaves 21 bits available (the remaining 5 bits of the first octet, plus the full 16 bits of the second and third octets) to define the network portion. This results in the following calculation for possible networks:

2^21 = 2,097,152.

Each Class C network can accommodate up to 256 IP addresses (from 0 to 255 in the last octet), minus network and broadcast addresses, resulting in a practical limit for hosts. The design of Class C serves mostly smaller networks, making it popular among organizations that require many separate networks while accommodating fewer devices on each one.

Other classes like Class A and B have different structures and yields for network ranges, which do not align with the 2,097,152 network total found in Class C. Class D
