Let me explain, how this works. In this snapshot, client behaves
incorrectly. FQDN draft states that FQDN option MUST be sent and that
sending only option-request with FQDN is not enough. This is already fixed
in CVS. I expect to prepare another snapshot shortly (tomorrow maybe?)
For now, there's simple workaround: In client.conf use following syntax:
option fqdn any.name.it.will.be.ingored.anyway
Make sure that you have the DNS server configured properly. In case of DNS
server misconfiguration (e.g. does not accept updates at all), there will
by ugly delays and timeout on the client side.
If you are not in a hury, I suggest you to wait for this next snapshot. It
will be much more usable.

This won't work. FQDN works in the statefull mode only. To get FQDN
working, you have to obrain following parameters:
- IA containing at least one address
- DNS server (so Dibbler knows, where send updates to)

I will help you. Keep in mind that this is a work in progress, so there
are *A LOT* of things which are not production quality yet. But this kind
of feedback is especially appreciated. Thanks.

Good suggestion. I never had time to make some pretty pictures. Until
recently, Dibbler was used in simple configurations - server talking to a
client. But this has changed and the docs are about to be updated.
