yeah how does the server know that it is actual you? MAC address?

ah crap!! IPv6, same principles for subnetting?

account login details in the VoIP software or firmware. MAC would be
no good as you may run VoIP software cleint on multiple machines.

All the VoIP services I've tried to date have user/pass entries. Since
some of them are charging funds for outbound calls, I just hope these
strings are sent in some encrypted way (in case anyone cares, those
accounts I have tried so far are primarily for incoming calls and yet
to be given any funds... Some services allow inbound via US gateways (ie
PSTN numbers allowing onward calls to VoIP networks), and some might be
called direct by other users of the same network, without any charges)

It's very rare one needs to enter an IP address, unless DNS has failed.

You can add your own entries into your local 'hosts' file, so for me to
ping 8 remote servers I just type ping sv1 or ping sv8 but equally
I can 'ping jessica' to check my friend's connection in Boston, USA.

I assume instant messenger connections go via a remote server or can
it work peer to peer.
