Answer: A, C, and D
The IP addresses and subnet masks that are for use on
private networks are 10.0.0.0 ? Mask 255.0.0.0, 172.16.0.0
through 172.31.255.255 ? Mask 255.240.0.0, and 192.168.0.0
through 192.168.255.255 ? Mask 255.255.0.0. Usually,
networks that don?t connect to the global Internet use these
addresses. If these addresses are used in a network that
also uses a globally unique IP address or registered
address, the private addresses must be filtered with access
lists to avoid advertising them to the Internet.
