Which IPv4 prefix is a private address range?

Explanation:
Private IPv4 addresses are reserved blocks that are not routable on the public Internet and are intended for use inside organizations, usually with NAT to reach external networks. The well-known private ranges are 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. Among the given prefixes, 10.0.0.0/8 falls inside that private space, so it is a private address range. The other prefixes are designated for documentation and example use (TEST-NET-1, TEST-NET-2, TEST-NET-3) and are not meant for internal networks, so they aren’t private addresses.
