D) 169.254.0.0/16

Answer 1

The network that is not defined by RFC 1918 is 169.254.0.0/16.

Step-by-step explanation:

The network that is not defined by RFC 1918 is option D) 169.254.0.0/16.

RFC 1918 is a document that defines private IP address ranges that are reserved for internal use within private networks. These addresses are not routable on the internet. The ranges defined by RFC 1918 are:

1. 10.0.0.0/8 - This range includes all IP addresses from 10.0.0.0 to 10.255.255.255.
2. 172.16.0.0/12 - This range includes all IP addresses from 172.16.0.0 to 172.31.255.255.
3. 192.168.0.0/16 - This range includes all IP addresses from 192.168.0.0 to 192.168.255.255.

The address range 169.254.0.0/16 is an Automatic Private IP Addressing (APIPA) range, which is used when a device is unable to obtain an IP address from a DHCP server. This range is not defined by RFC 1918.
