Hello,

is it a limitation of kea or of the dhcp6 protocol? What is IAID then for? The 
IAIDs are different.

If I add hwaddress as a key, I suspect it is not real harware address but 
rather some hw-address part from the DUID so it is the same for all interfaces. 
Am I right?

So it seems I will have to create new vlan with the same purpose. What I would 
like to achieve is to have the host to be able to connect using either the 
cable or wifi. Both have the reservation (different ipv6 address).

Thanks

Marek
