My firewall logs are showing pings from within the mp3.com network ( 208.48.67.12, 208.48.67.17, 208.48.67.60 and so on) I searched google.com with those addresses, and I see that other people are being pinged too.

If I don't run a Gnutella client for a while, the pings slack off to once a day. Right now, I'm logging several a minute. Since MP3.com belongs to some label (Vivendi Universal) I am suspicious of their intent.

Perhaps RIAA or Vivendi or mp3.com are trying to keep track of people using Gnutella?
