Internet Telephony
Internet Protocol (IP) Network address translator (NAT) is a network address translation device that translates all outgoing traffic from one public address to another public address. It is commonly used on the Internet to allow multiple clients to share a single public IP address.
Multiple NATs connected to each other using a communication protocol that allows hosts to transmit packets to multiple ports. The hosts themselves have a private IP address, while the NATs have a public IP address. Each host is identified by a combination of an IP address and a port number. Packets from a host are addressed to the NAT address followed by a port number. The NAT device will choose a public IP address for the host, then translate the port number back into a private address for the host.
By combining these two features, NAT provides a number of benefits, including the ability for a private network to utilize the public Internet, and vice versa. This, combined with the ability to assign multiple public IP addresses to a single private network, has given rise to a wide range of uses, both on the Internet and in organizations.
