Answer options

• A. 10.172.76.200
• B. 12.17.1.20
• C. 172.15.2.250
• D. 172.31.255.100
• E. 192.169.32.10

Correct answer: A, D

Explanation

The addresses 10.172.76.200 and 172.31.255.100 fall within the ranges designated for private networks (10.0.0.0/8 and 172.16.0.0/12, respectively). In contrast, 12.17.1.20, 172.15.2.250, and 192.169.32.10 are not within those private ranges, making them unsuitable for private use.
