In the IPv6 address allocation scenarios, host self-generated
addresses are notionally conflicted with the network managed address
architecture. These addresses need to be registered in the networking
management plate for the purposes of central address administration.
This document introduces a generic address registration solution
using DHCPv6, and defines one new ND option and one new DHCPv6 option
in order to propagate the solicitations of registering self-generated
addresses. The registration procedure reuses the existing IA_NA in
the DHCPv6 protocol.
