NAT
Network Address Translation (NAT) technology translates IP addresses of a local area network to a different IP address for the Internet. Each computer on your network has a local IP address. When the router gets the data transmission to forward out to the Internet, the router puts a different IP address on the transmission. This way, whoever receives the data transmission doesn't know what the actual IP address of the computer is. The computer is hidden, safe from prying eyes.
An IP (Internet Protocol) address is a unique number that identifies every machine connected to the Internet. It is important to keep your IP address secure because hackers can gain control of your computer, or even launch an attack on other computers using your computer.
