Block IP Address Script

Use this script to block certain IPs from your webpage, by redirecting them to another site. Note that your web server must have SSI enabled (most Linux servers do), with the page using the correct extension (ie: .shtml) in order for this script to work. Furthermore, since this script relies on JavaScript to block the user (by redirecting the person to another site), if he/she disables JavaScript in the browser, the script will become futile.

Just insert the below script to the HEAD section of your page, and enter your list of IPs to block:

<script type="text/javascript">

//Enter list of banned ips, each separated with a comma:
var bannedips=["23.23.23.23", "11.11.11.11"]

var ip = '<!--#echo var="REMOTE_ADDR"-->'

var handleips=bannedips.join("|")
handleips=new RegExp(handleips, "i")

if (ip.search(handleips)!=-1){
alert("Your IP has been banned from this site. Redirecting...")
window.location.replace("http://www.google.com")
}

</script>
