Explanation

Port Address Translation (PAT), also called NAT overload, is considered the most convenient and secure NAT solution because it maps many internal private IP addresses to a single public IP address by differentiating connections using unique port numbers. This maximizes address conservation, hides the entire internal network topology behind one public IP, and is the dominant implementation in home and enterprise routers. Static NAT uses a dedicated one-to-one mapping, exposing internal hosts directly. Hiding NAT is a broader or vendor-specific term, but PAT is the most specific, efficient, and widely recognized implementation of many-to-one translation.
