What is a characteristic of private IPv4 addressing?
The correct answer is C. is used on hosts that communicate only with other internal hosts. Private IPv4 addresses are designated for use solely within private networks and are not routable on the public internet.
Question

Why each option
Private IPv4 addresses are designated for use solely within private networks and are not routable on the public internet.
While private IP addresses are often used for hosts that access outside organizations via VPNs, the VPN itself handles the secure tunnel, and Network Address Translation (NAT) typically translates the private IP for external routing, so this isn't a characteristic of the private IP itself.
Private IP addresses inherently do not allow endpoints to communicate across public network boundaries; NAT is required to translate them to public IPs for such communication.
Private IPv4 addresses, as defined in RFC 1918, are specifically reserved for use on hosts that communicate only with other internal hosts within a private network, and they are not routable across the public internet.
Using private IP addresses, especially with NAT, often adds complexity to network design and troubleshooting rather than reducing it.
