One or more processors are configured to associate a first local IP address with a computer while the computer is connected to a first network access node thereby providing the computer with access to a network. The first local IP address is one of a plurality of local IP addresses used on the network. The one or more processors monitor transmissions received from the first network access node to determine when the computer requests an Internet transaction. When the computer requests an Internet transaction, a first one of the globally unique IP addresses is associated with the first local IP address thereby allowing the computer to conduct the Internet transaction. The first globally unique IP address is disassociated from the first local IP address after termination of the Internet transaction and is then available for association with any of the local IP addresses used on the network.
