• javascript

• ssi

• 1 What is your server side language? – Shadow Wizard Commented Jan 12, 2011 at 15:38
• Duplicate of stackoverflow./questions/391979/… (Unless you have a server-side language, in which case it would be possible, but it wouldn't be only Javascript). – qJake Commented Jan 12, 2011 at 15:38
• 1 could you give a bit more info about your environment, both above look to be classic ASP snippets. – trickwallett Commented Jan 12, 2011 at 15:39
• 2 @SpikeX -- the question here looks like the questioner is using JScript in a Classic ASP environment, which makes this a pletely different question than a question about getting the user's IP with client-side JavaScript. – Sean Vieira Commented Jan 12, 2011 at 15:40

Use the following code for to get the IP Address in ASP Classic

<%
Dim UserIPAddress
UserIPAddress = Request.ServerVariables("HTTP_X_FORWARDED_FOR")
If UserIPAddress = "" Then
UserIPAddress = Request.ServerVariables("REMOTE_ADDR")
End If
%>

Most web servers (I'm assuming you're using IIS) provide this information in the REMOTE_ADDR Environment Variable.

Your samples are trying to get at the server's variables with Classic ASP and Server Side Includes, both of which are turned off by default on modern IIS web servers. You may need to enable classic ASP or SSI, or use the ServerVariables property using ASP.NET

Try this:

<script type="text/javascript">
    var ip = "<%=Request.ServerVariables("REMOTE_ADDR")%>";
    alert(ip);
</script>

Assuming this is .asp page you should see alert with your ip address.

You cannot do this with JavaScript alone, it looks to me like you're trying to use server side code on the client, that doesn't work.

The easiest, fastest (and ugliest) of doing this would be to output the IP on the s*erver side*, into a script tag on the page that's being send to the user.

No idea which language you're using on the server side, so I'll provide you some pseudo code.

echo '<script type="text/javascript">var USER_IP = ' + getRemoteAddess() + ';</script>'

This will introduce a global variable called USER_IP into the page, make sure that the code that uses this variable es after the above script tag.

You cannot get the IP using pure Javascript. The two solutions you provided require server-side scripting.

try

ip = '<%= Request.UserHostAddress %>';

For the record in case anyone is looking for the PHP solution, you'd just do it like this:

<?php echo $_SERVER['REMOTE_ADDR']; ?>

For example, if you were passing it in a JS array, it would look like this:

tr._setSomeVar(5, "Remote Address", "<?php echo $_SERVER['REMOTE_ADDR']; ?>", 9);
