Connection to 224.0.0.252

A tester reported that my program caused Zonealarm firewall to come up requesting permission for my program to access the internet, specifically to IP 224.0.0.252. I've tried looking this up and it seems to be something to do with local networks or domain look ups or something but I don't really understand it. What's more concerning is my program, to my knowledge, shouldn't access the internet/network at all. Any thoughts?

Link-local Multicast Name Resolution.

That's interesting. Strange that a program with no network code in there would do that.
Although you do worry me a little with "to my knowledge"... :-)

strange, maybe the tester made a mistake?

Or maybe Skidracer put code in there to install spyware on every PC that a blitz program is run on !!11

More specifically I would fire up Wireshark and see what specifically the program is looking for in those broadcasts.
