Which of the following address ranges are private IP addresses? You must select all that apply for full credits.

172.16.0.0/24
10.0.0.0/12
172.16.0.0/12
10.0.0.0/8
192.168.0.0/24
192.168.0.0/16

Answer 1

The private IP address ranges are 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16, so 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, 172.16.0.0/24, and 192.168.0.0/24 are private. The 10.0.0.0/12 range is not a designated private IP range.

Step-by-step explanation:

The following IP address ranges are considered private according to RFC 1918 standards for IPv4:

• 10.0.0.0/8: This range includes all IP addresses from 10.0.0.0 to 10.255.255.255.
• 172.16.0.0/12: This range includes IP addresses from 172.16.0.0 to 172.31.255.255.
• 192.168.0.0/16: This range includes IP addresses from 192.168.0.0 to 192.168.255.255.

Thus, from the options provided, 172.16.0.0/24 and 192.168.0.0/24 are subsets of the larger private address ranges 172.16.0.0/12 and 192.168.0.0/16, respectively. Therefore, they are also private. However, 10.0.0.0/12 is not a recognized private range because the correct private range is 10.0.0.0/8.
