| The last incoming IP is 169.254.205.18, but it's not the same IP each time.

| I've searched the internet, and found several message boards that offer tech 
| help where people were told "Don't worry about it, allow it.".
| 
| Also NIS itself suggests that I allow it.
| 
| I've been denying it each time because it's INCOMING, it wasn't coming in 
| yesterday, I don't know what it is or why it might be trying to send me UDP 
| packets, and I don't think it has my best interests in mind.  ;-)
| 
| So now I have some questions:
| 
| 1) What is it, and why did it all of the sudden start picking on me?  Of 
| course I suspect it's a worm looking for an open socket.
| 
| 2) Why is NIS suggesting I allow it?
| 
| 3) How is a remote IP able to reach me through my LinkSys router?  Here is 
| my current IP info:

| At first I couldn't think of any changes I've made to bring this on, but now 
| I remember that I did install all of the Windows XP components listed under 
| "Networking Services" (UPnP UI, Simple TCP/IP services, etc.) last night.
| 
| Is that what's causing this?  Also is that why I have these funky IP's 
| listed under IPConfig <above> that I've never seen before?
