Definition
Network Address Translation (NAT) is a method used by routers to translate private (internal) IP addresses to a single public IP address when communicating with the internet, and vice versa. NAT conserves the limited number of public IPv4 addresses by allowing multiple devices on a private network to share a single public IP. It also provides a basic layer of security by hiding internal network structure from external networks.
Example
“All 50 computers in an office access the internet through a single public IP address thanks to NAT performed by the router.”
