The DHCPv4 Leasequery capability [RFC4388] extends the basic DHCPv4 capability [RFC2131] [RFC2132] to allow an external entity to query a DHCPv4 server to recover lease state information about a particular IPv4 address or client in near real-time.

Active DHCPv4 Lease Query
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".
