	Title           : DHCPv4 lease query by Relay Agent Remote ID
	Author(s)       : P. Kurapati, B. Joshi

Some Relay Agents extract lease information from the DHCP messages
exchanged between the client and DHCP server.  This lease information
is used by relay agents for various purposes like antispoofing and
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.  The existing lease query mechanism is
data driven, which means that a relay agent can initiate the lease
query 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 a new query
type, query by Remote ID, to address these issues.
