再谈PHP获取访客【真实】IP问题
通过IPIP.NET获取的IP的信息是正确的。访问IP访问也正确。
路由器显示公网IP为:222.40.147.11
。IPIP.NET/IP138.com获取到的IP都是222.40.147.11
。显示河南洛阳 铁通
。这没问题。
但是我在国外VPS上挂了一个脚本,http://45.32.10.32/index.php
。_SERVER
里根本没有222.40.147.11
。而且获取的REMOTE_ADDR
也是218.76.128.29
显示为湖南娄底 电信
.
IPIP.NET和IP138.com是怎么获取到我的IP的?
Ps: 跟Forwarded
和代理
没有任何关系。

最可能的一种情况是:你使用的运营商实力不足,只能租用大运营商的网络。所以你通过 ISP 的内部网络之后,会有多个出口 IP。对不同的目标 IP,可能会走不同的出口 IP。也观察到有轮询策略,即打开 ip138,IP 地址是 A,刷新一下,变成 B,再刷新一下,又变回 A。
用route命令跟踪看看
