I have 2 seperate websites that deals with entirely different subjects. I maintain a database of users who visit my websites. Yesterday as i was going through the user records I noticed someone has been frequently visiting both my websites for the past 2 years(its always the same IP address), and that too from a place that has no relevance to my target audience(country/language).

IP: 183.97.XXX.XXX
Browser Info: Firefox/7.0.1
Javascript: Never enabled(for the past 2 yrs)

Strangely, this user has been visiting only the "homepage" of both my sites.

Is there any way I can find out who this user is? Or atleast I should be able to redirect my home page to "Sorry page not available for this country" to this user IP alone" ? I want the php to do this redirect(or something similar to that). May be I can load this php file through <iframe> inside my homepage.html?

Any ideas?
