I log onto my computer this morning to receive a message from Comodo Firewall saying "New Private Network Detected! 169.254.209.146/255.255.0.0"

I have never seen this IP in my life and after looking it up, I found it is coming from Washington D.C. - I live in NJ.

In my home network I have my Windows XP computer, two Windows 7 laptops, a Windows XP laptop, an iPad, my Xbox-360, and my Nintendo Wii.

Forgive me, for I am not very knowledgeable on these kinds of things.

So what I would like to know is:
1) How did this computer connect to mine??
2) What can I do to disconnect my computer from this other random Network??
3) What can I do to keep my computer unable to connect to these random networks??

Thanks in advance.

169.254.X.X is a local only IP (same as 192.168.X.X). You may want to scan your PC's (all of them, not just the one that had the alert) with anti virus/malware software to make sure you're safe.

No idea how you got Washington D.C from the lookup. I even ran a look up on it, and it showed it was link-local by ARIN.
