A New Internet-Draft is available from the on-line Internet-Drafts
directories.

        Title           : DHCPv4 Leasequery by relay agent remote ID and circuit ID
        Author(s)       : P. Kurapati, D. Rao, B. Joshi
        Filename        : draft-kurapati-dhc-leasequery-by-remote-id-00.txt
        Pages           : 27
        Date            : 2008-2-16

Some Relay Agents extract lease information from the DHCP message
   exchanged between the client and DHCP server.  This lease information
   is used by relay agents for various purposes like antispoofing,
   prevention of flooding.  RFC 4388 defines a mechanism for relay
   agents to retrieve the lease information from the DHCP server as and
   when this information is lost.  Existing leasequery mechanism is data
   driven which means that a relay agent can initiate the leasequery only when it starts receiving data from/to the clients.  In certain
   scenarios, this model is not scalable.  This document first looks at
   issues in existing mechanism and then proposes new query types, query
   by remote ID and query by circuit ID, to address these issues.
