Which of the following IP addresses is classified as a private IP address?

Private IP addresses are specified by the Internet Engineering Task Force (IETF) in the Internet Assigned Numbers Authority (IANA) guidelines. They are defined for use within a private network and are not routable on the public Internet, which helps conserve the limited number of available IP addresses.

The IP address ranges reserved for private use are as follows:

1. The range 10.0.0.0 to 10.255.255.255, which provides a significant number of addresses and is used primarily in large networks.

2. The range 172.16.0.0 to 172.31.255.255, which can accommodate moderate-sized networks.

3. The range 192.168.0.0 to 192.168.255.255, commonly used in home and small office networks.

Given that 192.168.1.1 falls within the 192.168.x.x range, 10.0.0.1 is within the 10.x.x.x range, and 172.16.0.1 is within the 172.16.x.x to 172.31.x.x range, all three addresses are categorized as private IP addresses.

Therefore, each option represents a valid
