The Dynamic Host Configuration Protocol for IPv6 (DHCPv6) has been extended with a Leasequery capability that allows a client to request information about DHCPv6 bindings. That mechanism is limited to queries for individual bindings. In some situations individual binding queries may not be efficient@ or even possible. This document expands on the Leasequery protocol@ adding new query types and allowing for bulk transfer of DHCPv6 binding data via TCP.
