问题描述

如何确定给定的IP地址是官方Internet地址还是内部Intranet IP地址?

How can I find out whether a given IP address is an official internet address or an internal intranet IP address?

推荐答案

内联网IP通常在私有IP范围内:

Intranet IP's are often in the private IP range:

10.0.0.0 through 10.255.255.255
172.16.0.0 through 172.31.255.255
192.168.0.0 through 192.168.255.255

这些不适用于Internet IP地址.

These are not usable for internet IP addresses.
