However, it would be logical to extend the DHCPv6 protocol to allow for
registration of the workstation address in DNS by the DHCPv6 management
server  to be requested (similar to DHCPv4).

The DHCPv6 management server needs to become aware of new IP addresses
already to send ordinary unicast responses, and a DHCPv6 server is a
central server
 that can be entrusted with the capability to update DNS records,

with no need for overtrusting each individual client,  or requiring a
complicated
authentication scheme on DNS servers, for clients to update DNS records
corresponding to their own hostname,  without each client's credentials
being capable of updating any other machine's DNS entry.
