@ -74,7 +74,17 @@ In other words, the DHCID RR maps an FQDN to the client to whom it
belongs, and thereafter changes to that mapping can only be done by
or at the behest of that client.
Currently, D2 conflict detection is always performed.
Conflict resolution can be indirectly enabled or disabled via
the configuration parameter ``ddns-use-conflict-resolution``, supported
by both ``kea-dhcp4`` and ``kea-dhcp6``. The servers use this parameter to
set a flag within each NameChangeRequest they send that tells D2
whether conflict resolution should be employed for that request.
By default, conflict resolution is enabled. For more details, please refer
to discussions of ``ddns-use-conflict-resolution`` in :ref:`dhcp4-ddns-config` and :ref:`dhcp6-ddns-config`.
When conflict resolution is disabled, D2 still adds DHCID RRs but does
not use them to enforce client ownership of DNS entries. Disabling it should
only be used after careful consideration.
