            Dynamic Host Configuration Protocol Options for
          Coordinate-based Location Configuration Information

                  draft-ietf-geopriv-rfc3825bis-17.txt

Abstract

   This document specifies Dynamic Host Configuration Protocol Options
   (both DHCPv4 and DHCPv6) for the coordinate-based geographic location
   of the client.  The Location Configuration Information (LCI) includes
   Latitude, Longitude, and Altitude, with resolution or uncertainty
   indicators for each.  Separate parameters indicate the reference
   datum for each of these values.  This document obsoletes RFC 3825.
