Which of the following is a private IP address range?

Explanation:
Private IP addresses are blocks reserved for internal networks and are not routed on the public Internet. The standard private ranges are 10.0.0.0 to 10.255.255.255, 172.16.0.0 to 172.31.255.255, and 192.168.0.0 to 192.168.255.255. Among the options, the first range sits squarely in the 10.x.x.x private block, so it is a private address range. The other choices are not private: 8.8.8.0/24 is a public Google DNS address, 192.0.2.0/24 is reserved for documentation and examples, and 172.64.0.0/24 falls outside the private 172.16.0.0/12 range.
