我如何获得第一个IP地址范围？

Question

I wanna show two first range of an IP. For example, I have 127.0.0.1. I wanna get 127.0 and use this example:

127.0.0.1 show 127.0
192.168.1.6 show 192.168

How can I do that?

I tried $_SERVER['REMOTE_ADDR'] but it shows the whole IP address.

Use explode,

$nums = explode(".", "192.168.1.6") ;
echo $nums[0]. "." .$nums[1]; //192.168
