Obtaining the users IP Address

[mike55]

Hi all

 

I am trying to obtain the user IP address, to determine what country that they are comming from. The purpose of this information is to redirect the user to a particular page that is configured for the individual country.

 

Any suggestions on how to achieve this? So far I have managed to obtain the IP address of the server, but not the other way around.

Request.UserHostAddress should do the trick.

Many Thanks for the reply. Here is the code that I have started using:

   Private Sub DetermineUsersIPAddress()
       'Response.Write(Request.ServerVariables("REMOTE_ADDR"))
       Dim strIp As String

       strIp = Request.ServerVariables("HTTP_X_FORWARDED_FOR")
       If strIp = "" Then
           strIp = Request.ServerVariables("REMOTE_ADDR")
       End If

       Response.Write(strIp)
   End Sub

 

Now the next step is to find the country that the IP address belongs to.

'.Net 2.0
Dim host As String
host = System.Net.Dns.GetHostEntry(Request.UserHostAddress).HostName

'.Net 1
Dim host As String
host = System.Net.Dns.GetHostByAddress(Request.UserHostAddress)

 

The variable host should contain the fully qualified domain name - the country might be obtainable from parsing this out. Be aware this is not 100% (probably nowhere near in fact.)

 

You might find a better solution is to run a WHOIS query agains the IP address -
