This is where Network Address Translation (NAT) steps in. NAT is a way of connecting multiple computers in a private LAN to the Internet when a small number of public IP addresses are available. Typically a home Internet user is provided with 1 public IP address by an ISP for the whole house to connect to the Internet. NAT is the magic that makes this possible.
