Which statement about private IPv4 addressing is correct?

Private IPv4 addresses (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) are reserved for use within private networks and are not globally unique. This means they can be used by anyone without needing to register them with an authority like IANA, making them "usable without global tracking or registration." They are not routable across the public Internet; Network Address Translation (NAT) is required to translate them into public IP addresses for Internet access. The number of addresses varies significantly by block, with the 10.0.0.0/8 range alone containing over 16 million addresses, far more than 65,536. IANA allocates public IP address blocks and autonomous system numbers, but not private IP addresses for individual use.
