I think that this third ldif may be a bit more along the lines of what
you are looking for. I have shown the v4 / v6 split, combined with the
tree setup from option 2. I have tried to keep things like locations
unique, and only to split v4 / v6 when necesarry. Again, this is tested
to generate a working config with pultney/v4 in ISC-dhcp excluding
aforementioned known issues.
