                        Active DHCPv4 Lease Query

Abstract

   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 (RFC 4388).  That mechanism    is limited to queries for individual bindings.  In some situations,    individual binding queries may not be efficient, or even possible.    In addition, continuous update of an external requestor with    Leasequery data is sometimes desired.  This document expands on the    DHCPv4 Leasequery protocol, and allows for active transfer of near    real-time DHCPv4 binding information data via TCP.  This document    updates RFC 6926, "DHCPv4 Bulk Leasequery".
