You can get it using Request.ServerVariables["REMOTE_ADDR"] or Request.ServerVariables["HTTP_X_FORWARDED_FOR"].
See this function:

C#

public static string GetIPAddress()
{
    System.Web.HttpContext context = System.Web.HttpContext.Current;
    string sIPAddress = context.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
    if (string.IsNullOrEmpty(sIPAddress)) {
        return context.Request.ServerVariables["REMOTE_ADDR"];
    } else {
        string[] ipArray = sIPAddress.Split(new Char[] { ',' });
        return ipArray[0];
    }
}
