Network Address Translation (NAT) is a mechanism to translate the IP address of a computer or group of computers into a single public address when the packets are sent out to the Internet. By translating the IP address, only one IP address is publicized to the outside network. Since only one IP address is visible to the outside world, NAT provides additional security and it can have only one public address for the entire network instead of having multiple IP addresses.
