$_Server['Remote_Addr'] Not Giving the Right Ip Address

$_SERVER['REMOTE_ADDR'] not giving the right ip address

<input type="hidden" name="ip" value="<?php echo $_SERVER['REMOTE_ADDR']; ?>" />

Don't do that. Get the request from $_SERVER when the form is submitted. Getting it when the form is generated and storing it in the form just gives people the opportunity to change it.

Does this IP address normally happen when I use it in a localhost (XAMPP)?

Yes. Getting the local IP (IPv6) address is normal when you request a page from localhost.

$_SERVER['REMOTE_ADDR'] not returning IP address

When you have a server on say your laptop, and you try to access it from the same laptop, the website sees it as it self and is represented in many different ways, and here are a few:

127.0.0.1
::1
localhost

To see the IP of your computer you can do the following:

1. Put your website on a remote server then access it, this will give you your Public IP address.
2. Put your website on another server on the same network and access it from a different computer on that network, and this will give the internal IP address for that computer.

Why is $_SERVER['REMOTE_ADDR'] showing a wrong ip?

I don't care if they are behind a proxy, VPN, etc;

You have to, if they are using a VPN, or a proxy, or NAT then $_SERVER['REMOTE_ADDR'] will contain that ip and not of the user, and that is what you're getting.

UPDATE: I've talked to the specific user in question and he said he is NOT using Google Translate. Why else would a Google IP show in REMOTE_ADDR?

That Google IP you have mentioned in your OP belongs to google-proxy-64-233-173-164.google.com which is the proxy that this visitor's computer or ISP is using

If you were to check HTTP_X_FORWARDED_FOR or HTTP_CLIENT_IP You would get that information

$ _SERVER ['REMOTE_ADDR'] return IP of server, not visitor IP

you may use this function

function getRealIpAddr()
{
    if (!empty($_SERVER['HTTP_CLIENT_IP']))   //check ip from share internet
    {
      $ip=$_SERVER['HTTP_CLIENT_IP'];
    }
    elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))   //to check ip is pass from proxy
    {
      $ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
    }
    else
    {
      $ip=$_SERVER['REMOTE_ADDR'];
    }
    return $ip;
}

$ipaddr = getRealIpAddr();

Load Balancer $_SERVER['REMOTE_ADDR'] Not working

Your webserver receives HTTP requests from the Amazon ELB. Therefore, the remote address will always be one of the ELB ip addresses.
If you need the remote host's address from behind the ELB, get it from HTTP header "X-Forwarded-For".

IP Address of the machine in PHP gives ::1 but why?

::1 is the actual IP. It is an ipv6 loopback address (i.e. localhost). If you were using ipv4 it would be 127.0.0.1.

If you want to get a different IP address, then you'll need to connect to the server through a different network interface.
