If you have many visits from Reston, Virginia, that's because it's the home-base for all America Online / AOL users. Every AOL user in the world shows up as Reston, VA. Since AOL has millions of users, you'll see a lot of activity from that city, but the actual person could be anywhere. There's no way to find out the real location.

It could also be a search engine spider, a real person who loves your art, or an office where many people are admiring your work. It could be another website that indexes art sites.

In any case, we'll never know the exact reason for high visit stats from one IP address but it's nothing to fret over.
