Ok, I only have a small network.
But I've assigned to all known MAC adresses IP adresses in the
dhcpd.conf from the alix board (dhcp server). These contain desktop
machines, laptops, frontends, a squeezebox, even a TV, the media server
(mythbackend and squeezeboxserver).
These are around 20 addresses and for me it's easier like that to not
make a complete mess.
This alix board runs great. The bigger problem is the router from my
ISP. So I have switched it's dhcp server off and use a separate one on
that alix board.
The reason why I did that is actually because earlier I thought I would
be able to use it as the master backend that starts slave backends to
record and transcode, etc.
But meanwhile I learned that it won't be possible to have such a small
machine to only control backends and not do anything big on its own.
Now - since I have switched from a single backend/frontend combo to a
master backend without frontend last December - it may be better to
remove the alix board and run dhcp and dns server on the master
backend... But then I won't be able to shut it down (although until now
it runs 24/7)...
So most part of my LAN may just be a toy ;-)
And I actually wouldn't need bind9 :-)

I already have looked at the bind9 configuration and zone files. But
only when I directly wanted to set up dynamic dns. This may have been a
Thanks alot for your advices!
