How to use DHCP name protection in dual stack network

Question

Hi,

we are using Windows DHCP server for a dual stack network. Name protection is configured and works well, except for one small thing:

The non-windows machines have only one DNS record either A or AAAA but not both.
If the machine registers first the A reocrd incl. the corresponding DHCID record, the AAAA record is refused with eventid 10025 from DHCP-Server "as there is probably an existing client with same FQDN already registered with DNS." (which obviously is the existing A record).

If it is the other way round, the A record fails with the same error message but event id 1340.

How can I get it done, that also non-windows machines can register both addresses?

Thank you in advance
