What is a characteristic of private IPv4 addressing?
The correct answer is C. used without tracking or registration. Private IPv4 addresses are designated for use within private networks and do not require global registration or tracking. They are designed for internal use and cannot be routed directly over the public internet.

Why each option
Private IPv4 addresses are designated for use within private networks and do not require global registration or tracking. They are designed for internal use and cannot be routed directly over the public internet.
The specific number of available addresses varies greatly by private range; for example, 10.0.0.0/8 offers over 16 million addresses, not just 65,536.
IANA issues public IP addresses and autonomous system numbers, not private IP address ranges for specific organizations; private addresses are locally chosen from predefined ranges.
Private IPv4 addresses, as defined in RFC 1918, are reserved ranges intended for use within private networks. These addresses are not globally unique and are used without any form of tracking or registration by internet authorities.
Private IP addresses are non-routable on the public internet and must be translated (e.g., via NAT) to public IP addresses to traverse the internet, regardless of an outbound ACL.
