In a Class C network, the subnet mask is typically 255.255.255.0, which means the first three octets are used for the network identification and the last octet is used for host identification. Each octet in an IPv4 address contains 8 bits, making a total of 32 bits for the address.

For a Class C network, the last octet (8 bits) is available for host addresses. To calculate the number of possible hosts, you can use the formula:

2^n - 2,

where "n" is the number of bits available for host addresses. The "-2" accounts for the network address and the broadcast address, which cannot be assigned to hosts.

In a Class C network:

  • n = 8 (since the last octet is for hosts)

So, the calculation becomes:

2^8 - 2 = 256 - 2 = 254.

This means there are 254 usable host addresses in a Class C network. However, when looking solely at "how many possible hosts" refers to the total count including the unusable addresses, which would be 256.

The correct interpretation of the question suggests that the context was directed towards the total number of addresses in
