A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Dynamic Host Configuration Working Group of the IETF.

	Title		: DHCP Lease Query

Access concentrators that act as DHCP relay agents need to determine
the endpoint locations of IP addresses across public broadband access
networks such as cable, DSL, and wireless networks.  Because ARP
broadcasts are undesirable in public networks, many access
concentrator implementations 'glean' location information from DHCP
messages forwarded by its relay agent function.  Unfortunately, the
typical access concentrator loses its gleaned information when the
access concentrator is rebooted or is replaced.  This memo proposes
that when gleaned DHCP information is not available, the access
concentrator/relay agent obtains the location information directly
from the DHCP server(s) using a new, lightweight DHCPLEASEQUERY
message.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
		
		
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
