<P> Network address translation ( NAT ) is a method of remapping one IP address space into another by modifying network address information in Internet Protocol ( IP ) datagram packet headers while they are in transit across a traffic routing device . The technique was originally used for ease of rerouting traffic in IP networks without readdressing every host . In more advanced NAT implementations featuring IP masquerading , it has become a popular and essential tool in conserving global address space allocations in face of IPv4 address exhaustion by sharing one Internet - routable IP address of a NAT gateway for an entire private network . </P>
