Connecting a large number of hosts to the global Internet using a smaller number of public (external) IP address, thereby conserving IP address space.

Is NAT still used?

But the days of Nat breaking applications have long since gone. Today, applications are written with the assumption that Nat will be used. This means that embedding IP addresses inside data packets – always a violation of networking standards – is now considered a poor coding practice.
