Which IP address class supports the largest number of networks?

The correct answer is Class A because it supports the largest number of networks compared to the other classes.

In Class A, the first octet (the first 8 bits) of the IP address is used to identify the network, while the remaining three octets (24 bits) are used for host addresses within that network. This structure allows for a very large number of possible networks, specifically 128 (from 0 to 127 in the first octet), although Class A typically starts from 1. This vast allocation permits a maximum of approximately 16 million hosts per network, further emphasizing its capacity for extensive networking.

In contrast, Class B allows for 16,384 networks, using the first two octets for network identification while allocating the last two for hosts, thus supporting up to 65,534 hosts per network. Class C, on the other hand, supports the fewest networks with around 2 million networks due to its configuration of using three octets for network identification and only one for hosts, accommodating up to 254 hosts per network.

Class D is designated for multicast addresses and does not function as a traditional class for defining networks and hosts in the same way as A, B, and C do. Consequently, Class
