Setup avahi

Hi,
I'm working on a project. My goal is, if someone plug the network-cable into
his client, it should find his server automatically.

This means I have to write a X.service file into /etc/avahi/services/ on
server.
Questions:
- As far as I understand, avahi is not used for setting up IP-Adress, am I
right? Or could I modify avahi-setting so it gives clients IP-Adress
automatically?
- Can I write any type into X.service? Or do I have to select a type of
DNS-SD service? If yes, where is a list of services (so I can look which
services fit best to my project)?
- Do I need port? I think it's necessary for finding a server.
- What should I do on clients in order to find the server automatically?
Optional question:
- Am I allowed to have 2 servers (with same port/service) so the clients
find 2 servers.

Thank you very much!

Hi everybode, I think I answered my question myself:

avahi can set IP automatically with ARP (169.254.0.0/16).

I was able to write any type of service. On the client-side the server with
given type is found.

Answer is: no.

I didn't test but I tried with avahi-discover and it seems it's possible.

Thank you very much!
