Which of the following addresses is not a private RFC 1918 range?

Explanation:
Private IPv4 addresses are reserved for use inside private networks and are not routable on the public Internet. RFC 1918 defines three blocks for private use: 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. The addresses 10.0.0.1, 172.16.5.4, and 192.168.1.1 all fall within these private ranges, so they’re private. The address 8.8.8.8 does not fall into any of those blocks; it’s a public address used by Google’s DNS service and is routable on the Internet.
