Which of the following IP address(es) can be assigned to an Internet interface? (Mark all the appropriate choices)

• A. $10.180.48.224$

• C. $192.168.20.223$
• D. $172.16.200.18$

Answer 1

The IP address which can be assigned to an Internet interface is a public IP address. Private IP address are found in the following ranges:

• From $10.0.0.0$ to $10.255.255.255$
• From $172.16.0.0$ to $172.31.255.255$
• From $192.168.0.0$ to $192.168.255.255$

Also, some special IP addresses (like the local loopback address $127.0.0.1$, multicast addresses) can’t be assigned to an Internet interface. In this question only answer $B$ does not belong to the range of private IP addresses.
