Indian Servers pinging your site over and over again?

I’m just posting because im not sure how to explain this. But when i was looking at the access logs yesterday it had one indian server pinging the site a good 200 times, it was mostly on the one page.

I also noticed there was a few other indian visitors doing the exact same thing but just far less.

Also of interest is according to the stat counter the resolution and browser of the same IP address changed everytime they refreshed the page (which was every minute).

Does anyone have any idea what this could be?
