Question:
The private IP address ranges specified by IPv4 are as follows: Class A includes addresses from 10.0.0.0 to 10.255.255.255, Class B includes addresses from 172.16.0.0 to 172.31.255.255, and Class C includes addresses from 192.168.0.0 to 192.168.255.255. Additionally, there are other non-routable numbers such as 127.0.0.1, which is the loopback address, and 169.254.0.0 to 169.254.255.255, which represents the automatic private IP addressing (APIPA) range. In Class A, the first octet of the address ranges from 0 to 127. For Class B, the first octet ranges from 128 to 191, and for Class C, the first octet ranges from 192 to 223. Numbers above Class C are reserved for other purposes.
