remote_addr 不返回 IPv4 地址

I am using xampp on localhost and when I use $_SERVER["REMOTE_ADDR"] it returns ::1 (also does this in phpinfo()). Why does it do this? I want it to return a normal ip address like 127.0.0.1. My operating system is windows vista.

推荐答案

::1 是一个 IPv6 地址 和 0:0:0:0:0:0:0:1 的缩写，即 环回地址到本地机器.所以 ::1 与 127.0.0.1 相同，只是通过 IPv6 而不是 IPv4.

::1 is an IPv6 address and an abbreviation for 0:0:0:0:0:0:0:1 that is the loopback address to the local machine. So ::1 is the same as 127.0.0.1 only via IPv6 instead of IPv4.
