Hi!
If you look over my previous message, you can see how I followed the
trail. The first thing I did was find the domain name using nslookup
224.0.0.2. I could have done it with ping -a 224.0.0.2 also. The
domain name looked rather generic, and the IP address looked odd, as I
mentioned, which made me think about trying the tools at Sam Spade
(which I already knew about) to get a more detailed report. The report
from one of the tools on the site says "IANA special use", and "Please
see RFC 3171 for additional information." I then used Google to look
up RFC 3171:
http://www.google.com/search?hl=en&ie=UTF-8&oe=UTF-8&q=RFC+3171&btnG=Google+Search,
and the first link describes that group of IP addresses. Finally,
looking through the last link I gave may help you identify what
program is attempting to use that P address. Several of the pages
mention IGMP, whatever that is.

Good advice is like good paint- it only works if applied.
