如何在Codeigniter中找到IP地址？

Question

I am using a following function to track the user's ip address. I run the application on localhost.

    $this->input->ip_address();

when I try to execute this function on my computer's localhost it returns ::1 and same thing I tryied on another computer it returns same ip address. my confusion is why it not showing the diffrent ip address for that two diffrent computers.

Answer 1

::1 is the loopback address in IPv6. Which is same as 127.0.0.1. That is localhost .

The code is correct. Which return the ip address. You can see different IP when running this code on server.

$ip = $this->input->ip_address();
