Network address translation

Network address translation (NAT) enables you to access the Internet safely without having to change your private network IP addresses.

IP addresses are depleting rapidly due to widespread Internet growth. Organizations use private networks, which allows them to select any IP addresses they want. However, if two companies have duplicate IP addresses and they attempt to communicate with each other, they will have problems. In order to communicate on the Internet, you must have a unique, registered address. Just as the name implies, NAT is a mechanism that translates one Internet Protocol (IP) address into another.
