The DHCPv6 protocol [RFC3315] specifies a mechanism for the assignment of IPv6 address and configuration information to IPv6 nodes. IPv6 Prefix Delegation for DHCPv6 [RFC3633] specifies a mechanism for DHCPv6 delegation of IPv6 prefixes and related data. DHCPv6 servers maintain authoritative information including binding information for delegated IPv6 prefixes.

                         DHCPv6 Active Leasequery


   The Dynamic Host Configuration Protocol for IPv6 (DHCPv6) has been    extended with a Leasequery capability that allows a requestor to    request information about DHCPv6 bindings.  That mechanism is limited    to queries for DHCPv6 binding data updates prior to the time the    DHCPv6 server receives the Leasequery request.  Continuous update of    an external requestor with Leasequery data is sometimes desired.    This document expands on the DHCPv6 Leasequery protocol and allows    for active transfer of real-time DHCPv6 binding information data via    TCP.  This document also updates DHCPv6 Bulk Leasequery (RFC 5460) by    adding new options.
