Laravel` $ request-> ip（）`不返回IP地址的最后一位

Question

I'm using Laravel 5, PHP 7, and Homestead, and for some reason when I try to access $request->ip() I get back 192.168.10.1. But in my /etc/hosts file I have 192.168.10.10 homestead.test. Then when I var_dump($request); I get the following

...
 'HTTP_HOST' => string 'homestead.test' (length=14)
 'REDIRECT_STATUS' => string '200' (length=3)
 'SERVER_NAME' => string 'homestead.test' (length=14)
 'SERVER_PORT' => string '80' (length=2)
 'SERVER_ADDR' => string '192.168.10.10' (length=13)
 ...
 'REMOTE_ADDR' => string '192.168.10.1' (length=12)

Has anyone seen this before where the last value gets trimmed from the IP address?

Answer 1

In your case, $request->ip() means REMOTE_ADDR, which is the IP(192.168.10.1) your browser is using.

SERVER_NAME and SERVER_ADDR is homestead.test and 192.168.10.10, that's your web host's name and your web host's IP.

One of your computer's IP is 192.168.10.1, your homestead's IP is 192.168.10.10. So when you access your PHP program, your browser is using 192.168.10.1 to connect to homestead's 192.168.10.10.
