A Location Information Server (LIS) is a service provided by an access network. The LIS uses knowledge of the access network topology and other information to generate location information for Devices. Devices within an access network are able to acquire location information from a LIS.

               Location Information Server (LIS) Discovery                    Using IP Addresses and Reverse DNS


   The residential gateway is a device that has become an integral part    of home networking equipment.  Discovering a Location Information    Server (LIS) is a necessary part of acquiring location information    for location-based services.  However, discovering a LIS when a    residential gateway is present poses a configuration challenge,    requiring a method that is able to work around the obstacle presented    by the gateway.

   This document describes a solution to this problem.  The solution    provides alternative domain names as input to the LIS discovery    process based on the network addresses assigned to a Device.
