Technical Summary
This document describes an extension to the DHCPLEASEQUERY exchange
described in RFC4388. The extension allows the querying agent to
immediately refresh its cache after a reboot using information that
is available to it (the remote id) rather than requiring it to make
LEASEQUERY requests as a result of information gleaned from traffic
over time.

RFC Editor Note
Please revise section 6, "Security Considerations," as follows:
OLD
This document does not introduce any new security concerns beyond
those specified in the original lease query protocol RFC 4388
[RFC4388] specifications.
NEW
This document inherits the security concerns present in the
original lease query protocol RFC 4388 [RFC4388] specifications.
This specification introduces one additional issue, beyond those
described in RFC 4388. A query by remote-id will result in the
server replying with a consolidated lease binding information.
Such a query, if done from an unauthorized source may lead to
leak of lease binding information. It is critical to deploy
authentication techniques mentioned in RFC 3118 to prevent such
unauthorized lease queries.
