Hi Lisi,

One of the two "servers" addresses you see is probably an IP multicast address your client has subscribed to (http://en.wikipedia.org/wiki/IP_multicast). I.e. your client listens to that address, although it is not its usual unicast address.
Hope this helps,

Regards,
Lars

Subject: [Wireshark-users] wireshark display of streaming audio

Hello!

I am trying to interpret the packet information given by Wireshark as a result of streaming audio.  

Once contact has been established between my router and the IP of the streaming server, contact is only between two servers that are nothing to do with me.  There appear to be no packets passing to me, or rather my router, at all, but I am listening to the music, and have been for over an hour (throughout which time there has apparently been nothing passed to my router).

And why does Wireshark quote my router's internal IP, and not its external one, when contact is being established in the first place?

These are probably not the right questions.  Google certainly thinks that they are not.  But I am hoping that a human being will be able to disentangle what I am saying, and answer the question that I ought to have asked.

Thanks,
Lisi
