So any Help?

推荐答案

你不能。

MAC地址不是通过互联网广播的，也不是用于通过互联网进行寻址。它们用于识别网络中直到路由器（或其他LAN / WiFi控制器）的设备，并由DHCP控制器转换为IP地址。从那时起使用IP地址（也可能不会离开本地区域：您的LAN IP地址与您的Internet IP地址不同）

You can't.
MAC addresses are not broadcast over the internet, nor are they used for addressing over the internet. They are used to identify equipment within a network up to the router (or other LAN / WiFi controller) and are converted to IP addresses by the DHCP controller. THe IP address is used from that point on (and may not leave the local area either: your LAN IP address is not the same as your Internet IP address)

此外，MAC地址不是独特。它们在网段内必须是唯一的，但整个网络中可以有多个相同的MAC。没有办法通过互联网用MAC地址唯一地识别机器。



我认为你将不得不研究计算机网络和TCP / IP ，路由，OSI模型，...在编写网络特定应用程序之前了解这些东西是如何工作的。

Also, MAC addresses are NOT unique. They must be unique inside a network segment, but there can be multiple identical MACs all over the network. There is no way to uniquely identify a machine over the internet with a MAC address.

I think you're going to have to study up computer networking and TCP/IP, routing, the OSI model, ... to understand how this stuff works before writing network specific applications.
