What is the private IP address range for Class A?

Explanation:
Private IPv4 addresses are reserved for use inside private networks and aren’t routable on the public Internet. For Class A, the private block is 10.0.0.0 through 10.255.255.255, a /8 range that provides over 16 million addresses. This designation comes from RFC 1918 and is the Class A private space. The other private blocks—172.16.0.0 through 172.31.255.255 and 192.168.0.0 through 192.168.255.255—belong to Class B and Class C private spaces, respectively. The range 192.0.0.0 through 192.0.0.255 is not private; it’s a special-use block. So the Class A private range is 10.0.0.0 to 10.255.255.255.
