What is the benefit of NAT?

Some benefits of NAT include: Reuse of private IP addresses . Enhancing security for private networks by keeping internal addressing private from the external network. Connecting a large number of hosts to the global Internet using a smaller number of public (external) IP address, thereby conserving IP address space.

What does NAT stand for?

The Recursive query is, when a DNS client directly gets the IP address of a domain, by asking the name server system to perform the complete translation.
