Glossary Definition for: NAT

Network Address Translation (NAT) is a method to translate IP addresses between networks. It also allows a single, public IP address to be used by multiple private IP addresses.  This aspect of NAT is essential for creating private networks in home and mobile routers.  It's also becoming a common tool for internet service providers to manage dwindling numbers of IPv4 network addresses until the new IP addressing system, IPv6, is fully implemented.
