Port Address Translation

<networking> (PAT) A function provided by some routers which allows hosts on a LAN to communicate with the rest of a network (such as the Internet) without revealing their own private IP address. All outbound packets have their IP address translated to the routers external IP address. Replies come back to the router which then translates them back into the private IP address of the original host for final delivery. Compare SOCKS. (1998-05-08)

address resolution

WIKIMEDIA DISAMBIGUATION PAGE

Address resolution; Address Resolution; Address translation (disambiguation)

<networking> Conversion of an Internet address into the corresponding physical address (Ethernet address). This is usually done using Address Resolution Protocol. The resolver is a library routine and a set of processes which converts hostnames into Internet addresses, though this process in not usually referred to as resolution. See DNS. (1996-04-09)

Network address translation

Network address translation (NAT) is a method of mapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device. The technique was originally used to bypass the need to assign a new address to every host when a network was moved, or when the upstream Internet service provider was replaced, but could not route the network's address space. It has become a popular and essential tool in conserving global address space in the face of IPv4 address exhaustion. One Internet-routable IP address of a NAT gateway can be used for an entire private network.

As network address translation modifies the IP address information in packets, NAT implementations may vary in their specific behavior in various addressing cases and their effect on network traffic. The specifics of NAT behavior are not commonly documented by vendors of equipment containing NAT implementations.
