Abstract
System and method for fully transparent IP mobility services for clients in a dynamic LAN Ethernet environment. The functionality within a proxy server, a combination of network address translation, proxy address resolution protocol, and proxy domain name service, allow the proxy server to support and provide full IP client functionality to any IP-enabled network device in any proxy server enabled LAN. The proxy server may be added to an existing Ethernet (or Ethernet-emulated) LAN. Once configured with the necessary subnet range, DNS, and IP pools, the proxy server provides support for any mobile device that enters the LAN.
