[solved] IPv6 address gotten via DHCPv6 (kea) lost

I just noticed that my main Windows-machine loses its IPv6 address gotten via DHCPv6 (kea) over the day. Seen twice today and haven't checked in the past (24.11-RELEASE).

Looked at it more closely, it is there but deprecated, which is wrong. It has the current prefix.

IPv6 Address. . . . . . . . . . . : 2001:***:***:9d00:9c56:***:***:***(Preferred)
IPv6 Address. . . . . . . . . . . : 2001:***:***:9d00:192:168:1:10(Deprecated)
Temporary IPv6 Address. . . . . . : 2001:***:***:9d00:78ac:44b0:bc74:ed57(Preferred)

~~Went back to ISC, no such problem.~~

Edit1: Same problem exists. Why, what has happened here.

Edit2: Ok, I disabled the DNS config for IPv6 a few days ago.

Unchecking this box disables the dhcp6.name-servers option. Use with caution, as the resulting behavior may violate RFCs and lead to unintended client behavior.

So it is a known fact, I will mark this as solved. There doesn't seem to be the possibility to give "none" as a IPv6-address for DNS. For now, I disabled DHCPv6 in LAN.
