Summary:         The document is well written, but I have a few comments and issues I'd like the authors to address.
Major Issues: None
Minor Issues: None
Editorial Issues:

General:
-----------
QGEN_1:
The text says that the document updates RFC 6926, but it is a little unclear to figure out exactly what is updated.
I think it would be good to have an explicit "Update to RFC 6926" section which explains exactly which parts are updated.

QGEN_2:
The draft talks about "secure mode" and "insecure mode" in a few places, and defined different procedures based on which mode is used.
However, there is no generic definition for "secure mode" and "insecure mode". I wonder whether it would be useful to add some text somewhere, e.g. to section 2?

Abstract:
------------

QA_1:

The text says:

"The Dynamic Host Configuration Protocol for IPv4 (DHCPv4) has been
              extended with a Leasequery capability that allows a requestor to
              request information about DHCPv4 bindings."

Please indicate in which specification (RFC?) this extension has been done.


Section 1 (Introduction):
---------------------------------

Q1_1:

The text says:

              "Requirements exist for external entities to keep up to date on the
              correspondence between DHCPv4 clients and their bindings."

Are these documented requirements, or generic requirements coming from the industry? Please clarify.


Q1_2:

The text says:

              "This document updates DHCPv4 Bulk Leasequery [RFC6926] in that it
              specifies the DHCPv4 server should close the TCP connection if..."

Is "should" the correct wording? Section 8.4 contains both MAY, SHOULD and MUST procedures, and I am not quite sure which procedure(s) the text above refers.
