         Option for a Location Uniform Resource Identifier (URI)
              draft-ietf-geopriv-dhcp-lbyr-uri-option-12

Abstract

   This document creates a Dynamic Host Configuration Protocol (DHCP) 
   Option for transmitting a client's geolocation Uniform Resource 
   Identifier (URI). This Location URI can then be dereferenced in a 
   separate transaction by the client or sent to another entity and 
   dereferenced to learn physically where the client is located.

1.  Introduction

   This document creates a Dynamic Host Configuration Protocol (DHCP) 
   Option for transmitting a client's geolocation Uniform Resource 
   Identifier (URI). The DHCP implementation of the client can then 
   make this location information available to upper layer protocols 
   for their usage.  This location URI points a Location Server 
   [RFC5808] which has the geolocation of the client (through means 
   not defined in this document).  In this scenario, the DHCP client 
   is a Geopriv Target (i.e., the entity whose geolocation is 
   associated with the location URI). 

   Applications using upper layer protocols within the Target can then 
   choose to deference this location URI and/or transmit the URI to 
   another entity as a means of conveying where the Target is located. 
   Dereferencing a location URI is described in [ID-SIP-LOC]. Conveying
