You have a subnet mask of 255.255.255.192. What represents the calculated CIDR?

The CIDR (Classless Inter-Domain Routing) notation represents the number of bits set to '1' in the subnet mask. In the case of a subnet mask of 255.255.255.192, we first convert it to binary:

• The first octet (255) in binary is 11111111.

• The second octet (255) is also 11111111.

• The third octet (255) is again 11111111.

• The fourth octet (192) in binary is 11000000.

When we combine these, the full subnet mask in binary looks like this:

11111111.11111111.11111111.11000000

Counting the '1's gives us a total of 26 bits. Therefore, the CIDR representation for this subnet mask is /26.

This indicates that the first 26 bits of the address are used for the network part, while the remaining bits can be used for host addresses within that subnet. This CIDR notation is significant for understanding the number of hosts that can be assigned within the subnet, as well as for routing purposes in networking.

Therefore, the correct CIDR representation for a subnet mask of 255.255
