3.3.1 NAT

NAT (Network Address Translation) is the translation between private IP and public IP, which allows private network users to visit the public network using private IP addresses.

With the explosion of the Internet, the number of available IP addresses is not enough. NAT provides a way to allow multiple private hosts to access the public network with one public IP at the same time, which alleviates the shortage of IP addresses. Furthermore, NAT strengthens the LAN (Local Area Network) security of the network since the address of LAN host never appears on the Internet.
