Is it a client server app or a P2P app?

What a total ignorance of the P2P world.
It appears that some education is needed for our candid friend here.

First, a little history. "THE" P2P app, the original Napster, was
shutdown because of its reliance on centralized servers.

<SNIP>

So yes, P2P usually means server, too.

And otherwise apps would still fall back to using 
DNS or anycast-IP as the locator service.
DCC on IRC uses the IRC server to communicate the ports used
for the transfer of data between the peers, the data is never
seen though.

Thus P2P has 2 aspects in this part:
 - location service
   (where is that user and where is that IP/port
    the app has to push it's traffic too/from)
 - the actual peers using the location service
   to find out where everything is.

The second part is really Peer-2-Peer, but before
that there has to be a communication with the (decentralized)
location service to actually find out where someone is.

Greets,
