Explanation

PAT (Port Address Translation), also called NAT Overload, maps many internal private IP addresses to a single public IP address by using unique port numbers to track each session. This is the standard mechanism used in home routers and enterprise networks to conserve public IP addresses. DNAT (A) translates a public destination IP to a private one (used for inbound traffic to servers). DNS (C) resolves hostnames to IP addresses. DMZ (D) is a network segment for publicly accessible servers - none of these allow multiple internal hosts to share one public IP.
