Abstract 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.

Introduction The DHCPv6 [RFC3315] protocol specifies a mechanism for the assignment of IPv6 address and configuration information to IPv6 nodes. IPv6 Prefix Delegation (PD) for DHCPv6 [RFC3633] specifies a mechanism for DHCPv6 delegation of IPv6 prefixes and related data.
