Correct Answer – Option A

The IP address 0.0.0.0/0 is the default route in the IPv4, known as zero address 0.0.0.0/0 in CIDR notation. The subnet mask /0 here specified all networks effectively. The other IP addresses are specifying the block of addresses. You can use a CIDR calculator to do some experiments with CIDR block options. Here is such as CIDR calculator –

Option A is correct. The IP address 0.0.0.0/0 matches all the IP addresses. Using the 0.0.0.0/0 IP address, you can define a CIDR range that will apply to all the destination addresses.

Option B is incorrect. The IP address 172.16.0.0/12 specifies a block of 1,048,574 addresses. So, it won’t represent all the destination addresses.

Option C is incorrect. The IP address 192.168.0.0/16 specifies a block of 65,534 addresses. So, it won’t represent all the destination addresses.

Option D is incorrect. The IP address 10.0.0.0/8 specifies a block of 16,777,214 addresses. So, it won’t represent all the destination addresses.
