Which of the following is NOT an IPV4 address range reserved for private networks?

Which of the following is NOT an IPV4 address range reserved for private networks?

• 172.16.0.0 - 172.31.255.255
• 163.168.0.0-163.168.255.255
• 192.168.0.0 - 192.168.255.255
• 10.0.0.0 - 10.255.255.255 

EXPLANATION

In the Internet addressing architecture, a private network is a network that uses private IP address space. Both, the IPv4 and the IPv6 specifications define private addressing ranges. These addresses are commonly used for local area networks in residential, office, and enterprise environments. Private IP address spaces were originally defined in an effort to delay IPv4 address exhaustion.

The Internet Assigned Numbers Authority (IANA) reserves the following IP address blocks for use as private IP addresses:

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

The first set of IP addresses from above allow for over 16 million addresses, the second for over 1 million, and over 65,000 for the last range.

Another range of private IP addresses is 169.254.0.0 to 169.254.255.255, but those addresses are for Automatic Private IP Addressing (APIPA) use only.
