A method is described for the discovery of a Location Information Server. The method consists of attempting to use a Dynamic Host Configuration Protocol (DHCP) option, followed by a URI-enabled NAPTR (U-NAPTR). DHCP options are defined for both IPv4 and IPv6 DHCP. This document also defines a U-NAPTR Application Service for a LIS, with a specific Application Protocol for the HTTP Enabled Location Delivery (HELD) protocol.
