@christianleo333 Thanks for the suggestion. I believe I'm (very slowly) working on this feature in the PR #1023. Maybe you could check the design and comment on it?

So the current design is that you can specify (1) the prefix length and (2) the host ID per domain. I wonder if that's what you are looking for with DEVICE_LOCAL_ADDRESS_IPV6. And, if that's the case, whether the proposed syntax makes intuitive sense to you. The syntax I'm currently working on would be yourdomain.com[::1234:5678:9abc:deff].
