Title : DHCPv4 Leasequery 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 [RFC4388] defines a mechanism for
relay agents to retrieve the lease information from the DHCP server
as and when this information is lost. The 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 a new query type, query by remote ID, to address these
issues.
