So, I noticed today that there are many domains that lead to my VHosts.
Here's one I found:
http://lickr.com - leads to one of my vhosts.
I noticed while trying to get it up on another computer, that it said the IP address was 127.0.1.1, which is the Localhost. So for some reason, Apache has set lickr.com up as one of my virtual host domains. I didn't do anything to contribute to this, it did it by itself...
