Network Address Translation (NAT)

If your computer can access the Internet, it must use TCP/IP. If you have your own home network with your own router, there is a chance that your computer has an IP address very similar to ours or someone else’s in your class—or the same address, in fact. How can two computers have the same IP address? Well, they can’t. This is a security technique called network address translation (NAT) in which one set of ‘‘private’’ IP addresses is used inside a network and a different set of ‘‘public’’ IP addresses is used by the router when it sends the messages onto the Internet.

What is the reasoning and importance of this type of security? Why is it necessary to perform this translation? How might NAT be used to protect large organizations?
