Currently it is only possible for the DHCPv6 prefix delegation, as we
know the use cases for this.

As for the address assignment case, can you describe the specific use
case for it? It would help us evaluate whether there are any
possibilities to achieve that with a current functionality.

It is possible to specify the timers for subnets. It is currently not
possible to specify them for classes or hosts. I believe we could
include timers for classes or hosts in the future but probably post 1.2
release.

There is currently no way to specify subnet specific options or class
specific options in MySQL. We are aiming to migrate most (if not all)
configuration to the database but this is a future.
