如何在PHP中找到我的真实IP地址（获取服务器的IP而不是访问者的IP）[重复]

Question

This question already has an answer here:

• $_SERVER[“REMOTE_ADDR”] gives server IP rather than visitor IP 6 answers

How do I find my real IP address?

If I do:-

$_SERVER['REMOTE_ADDR']

It gives me wrong IP Address (157.191.122.36), which I've checked as it gives me same values even when my site is accessed through different locations and countries.

This place somehow, gives me the right IP (64.74.66.230) at http://www.whatismyip.com/, but I can't get the same value through the above PHP code.

EDIT

I tried the URL mentioned in the comment. None of the solutions worked for me. It is clear now though that ehen using $_SERVER["REMOTE_ADDR"], I get the server's IP address rather than the visitor's.

$_SERVER['REMOTE_ADDR'] is the only reliable IP address you'll get - it's extracted directly from the TCP stack and is where the current connection was established from. This means if the user is connecting via a proxy, you'll get the proxy's address, not the user's.

Any of the other header-based ones are unreliable, as HTTP headers are trivial to forge. You can use the information from them, if you'd like, as long as you don't TRUST it.
