Redirect By IP

som1 have PHP script or java or can tell me how i can redirect all my visitors with the ip address that starts with 10.0. will be directed to Site A, otherwise they get directed to Site B


or some1 can modify this in PHP cuse this is ASP


<?
remoteIP = request.servervariables("REMOTE_ADDR")
if left(remoteIP,5)="10.0." then page="Site A" else page="Site B"
Response.Status = "301 Moved Permanently"
Response.AddHeader "Location", page
?>

 

if (substr($_SERVER['REMOTE_ADDR'], 0, 5) == '10.0.')
    $page = 'pageA';
else
    $page = 'pageB';
header('HTTP/1.1 301 Moved Permanently');
header('Location: gtfo.php');

PHP:

Though I would only use the 301 redirect when the IP condition matches. But then again, I don't know your exact situation.

 

thnx man but its dosent work som1 help me pls

i fund and this but i cant modify cuse i dont have knowlege in php

<?php
if ( getenv("REMOTE_ADDR") != "10.0.0.1" ) {
header("Location: http://otherhosthere");
}
?>

 

I decided to test it on my local server and online and it works in both cases. Can I ask what was the problem with my code? Was there an error? Did it display a blank page? etc.

 

thnx man with your it was blank page and not redirectet me ... i find script thnx man from all thnx the working script is this

<?
$visitor = $_SERVER['REMOTE_ADDR'];
if (preg_match("/200.xxx.xxx.xxx/",$visitor)) {
header('Location: http://google.com');
} else {
header('Location: http://yahoo.com');
};
?>

or download here

 

but i have another question how can i put more IP adreses here is just 1 but i need more IP


<?
$visitor = $_SERVER['REMOTE_ADDR'];
if (preg_match("/200.xxx.xxx.xxx/",$visitor)) {
header('Location: http://google.com');
} else {
header('Location: http://yahoo.com');
};
?>

 

Hmmm... that looks exactly like my code without the 301 header. Oh well.

200.xxx.xxx.xxx won't match any IP, "x" in the regex means a literal "x" and a "." represents any character, not a literal "dot".
Refer to: _http://www.regular-expressions.info/reference.html

Here is the proper regex to match an IP starting with 200.
^200
or:
200\.\d{1,3}\.\d{1,3}\.\d{1,3}

If you want to match more IPs, just post the list here as it is hard for someone new to regex to be able to do this.

If you want to try, use this template:

\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}

Code (markup):

Each \. represents a dot and the \d{1,3} represents a 1-3 digit number.

Replace \d{1,3} with the number you want to match and pipe these together.

Eg: to block 200.*.*.* and 10.0.*.*

Use:

(200\.\d{1,3}\.\d{1,3}\.\d{1,3}|10\.0\.\d{1,3}\.\d{1,3})

           note the pipe (|)  /\

Code (markup):

A shorter way is:

^(200|10\.0)\.

Code (markup):

Instead of:

if (preg_match("/213.163.105.50;189.234.345.543/",$visitor)) {

Code (markup):

Use:

if (preg_match("/(213\.163\.105\.50|189\.234\.345\.543)/",$visitor)) {

Code (markup):

Note the \. is needed to match a "literal dot", it will work with a normal "." but not for the reason you may think.

Also, instead of a colon to make a list of candidates, use a pipe (|). One last thing, when you use a pipe to make a list, the list must be enclosed in parenthesis "( and )".

Of course, if you want to blacklist full IPs, you do not need regex.

Just use:

if (in_array($visitor, array('213.163.105.50', '189.234.345.543'))) {
