Answer :
Final answer:
The number of usable host IP addresses on a network with a /26 mask is 62, as two addresses are reserved for the network and broadcast addresses.
Explanation:
In networking, a /26 mask equates to a subnet mask of 255.255.255.192. This effectively splits a typical Class C subnet into 4 subnets. The total number of IP addresses per subnet will be 64 (26 = 64), as the /26 means that 26 bits are being used for the network portion of the address, leaving 6 bits for the host portion. However, two addresses out of these are always reserved - one for the network address and one for the broadcast address. Therefore, the number of usable host IP addresses for a subnet with a /26 mask is 62.

The usable number of host IP addresses on a network with a /26 mask is 62.
The /26 subnet mask is used to divide a given IP address into two parts: the network portion and the host portion. With a subnet mask of 26 bits, the first 26 bits of the IP address are used to identify the network, while the remaining 6 bits are used to identify the host within that network.
Since 2 bits can represent 4 different values (2^2 = 4), 6 bits can represent 64 different values (2^6 = 64). However, the network address and broadcast address cannot be used as host addresses, leaving only 62 usable IP addresses for hosts on this network. This means that any device on this network will have an IP address with the same first 26 bits, allowing them to communicate with each other directly.
