which UDP adress/port should i use?
I’m a bit hazy on the concepts behind O.S.C. the udp system seems to work if i use the adress 127.0.0.1 and port 7400 as it uses in the example. is this the best configuration? i have no idea what the numbers are derived from.
how should i choose theses numbers?
(i’m sending data over UDP to and from max msp to a pluggo made VST in in Ableton Live)
it’s *fairly* irrelevant, as far as i know.
there are several ports that are reserved by the os (for such things as ftp and the like), but those are generally lower numbers.
really, you just need to make sure you are listening on the same port you are sending on, and check your max window for any error messages. if 7400 works, stick with 7400.
so what does the adress mean- can i change that?

127.0.0.1 is localhost – that should work on any machine.

Nope, not true; if the machines have gateways configured, they should
be able to route UDP packets without any problems.

On a Mac (or a Linux box), the file /etc/services gives a list of the
common IP ports and their standard uses.

on windows a localhost which is not working (I mean
is often a failure in the tcp/ip stack, and on *nix/linux it should
already be working because some service use this address.

The lists of the the assigned port can be found at
http://www.iana.org/assignments/port-numbers. If you don’t know
anything about port don’t use a port number < 1024 and I will
recommand using a port number in the range 49152 – 65535 which are
