Detailed explanation-2: -Network Address Translation (NAT) has been an effective technique used to insulate a private internal IP network and map these to a single external IP address.
Detailed explanation-3: -Network address translation (NAT), a feature found in many firewalls, translates between external and internal IP addresses. With NAT, a private network can use internal, non-routable IP addresses that map to one or more external IP addresses.
