winforms - Why does my windows forms app access the internet? -


As far as I know, I have not added any Internet access to my net windows applications. But every time it tries out an outgoing connection to 239.2525.255.250. I have no idea why this is happening. Is it in some clean framework?

Information for 23 9.255.255.250:

I think this is not a great deal reference to your view:

Questions for you:

  • How do you know that this is your windows app? Zone Alarm
  • Are you using multicast for something? No
  • Are you running any multicast apps or applications that can use UPNP? No
  • Are you doing any networking with your app? If so, what class are you using?

The next time you see the warning, try it out:

  get started> Run & gt; Cmd.exe: netstat / b / o  

This can give you more information about where the alert is coming from.
