Which statement describes private IPv4 addressing?

Private IPv4 addressing alleviates the shortage of public IPv4 addresses. Private addresses (e.g., 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) are not routable on the public internet and can be reused in different private networks. Network Address Translation (NAT) is used to translate private IP addresses to public IP addresses when devices in a private network need to access the internet. This allows many devices to share a single public IP address, conserving public IPv4 space. Private addressing does not provide unlimited address ranges, as the ranges are defined by RFC 1918. ISPs do not require private subnets to be advertised to the internet; in fact, they block them. While a network might have multiple endpoint listeners, this is not the primary purpose or defining characteristic of private addressing.
