Location Information Server (LIS) Discovery Using IP Addresses and Reverse DNS, April 2014
Discuss this RFC: Send questions or comments to firstname.lastname@example.org
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.
