A. B. C. D.Answer - A.
If you use an online CIDR calculator , you will get the number of subnets and hosts allowed.

The given IP address range is 11.11.253.0/24. This means that there are 24 bits dedicated to the network portion of the IP address, leaving 8 bits for the host portion. This gives us a total of 2^8 (or 256) possible values for the host portion of the IP address. However, some of these values are reserved for special purposes, such as the network address (11.11.253.0) and the broadcast address (11.11.253.255), leaving us with 254 usable IP addresses.
To calculate the number of subnets available, we need to determine how many bits are being used for the subnet portion of the IP address. In this case, none of the bits are specifically designated as subnet bits, so we can use all 8 bits for the host portion. This means that we have 0 bits available for the subnet portion, which gives us a maximum of 2^0 (or 1) subnet.
Therefore, the correct answer is:
B. 128 maximum number of subnets and 254 number of hosts
256 subnets is not possible as there are no bits reserved for the subnet portion. Additionally, 128 hosts per subnet is not possible since the maximum number of hosts for this IP address range is 254.
