    You mean the dynamic ip address of the web site/web server ? You have your site behind an adsl router that change the ip - correct ? and search that ip and how you see you outside ? - Or you mean the ip of your viewers ? – Aristos Dec 01 '12 at 11:14

The ip of the viewers are get from

Request.ServerVariables["REMOTE_ADDR"]

or 

Request.UserHostAddress

reference: http://msdn.microsoft.com/en-us/library/system.web.httprequest.userhostaddress.aspx

If the user is behind a proxy you may also need to check some more server variables as I describe them on this answer: https://stackoverflow.com/a/2514717/159270
