ABSTRACT
A group of creative engineers invented a technology that allows multiple devices to share one Internet connection and avoid the extra fees. The technology that allows multiple computers to share an Internet connection is so widely used that now more devices connect to the Internet using the technology than connect in the original way. This chapter explains how the technology works. The technology that allows devices to share an address is known as Network Address Translation (NAT). Because NAT is used in many ways, a variety of devices implement NAT technology. The NAT device most familiar to consumers is known as a wireless router. A wireless router connects user’s devices to a user’s Internet Service Provider. That is, instead of plugging one device into a Digital Subscriber Line or cable modem, a user connects the modem to the wireless router. Then, multiple devices can connect to the wireless router.
