In this issue, the editor will bring you about the method of modifying the IP and mac addresses of the public network. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

Recently, I need to use php to write a simulation program, the program needs to constantly change the public network IP address, and modify the local mac address.

After a period of research, I found a solution.

one. Public network address

The so-called public network address is relative to the intranet address. The intranet addresses are mainly in the following three formats: 192.168.x.xMague 10.x.x.xrex 172.16.x.x. In the case of home wireless routing, for example, the IP addresses you see through ipconfig are all intranet addresses. You can view the public network by visiting ip138.com.

1. I first applied for an adsl dial-up broadband. 120 yuan per month

two。 Modify the IP address by redialing

The related code is as follows:

This procedure realizes automatic dialing by calling external rasdial.

two. Mac address

Mac address, Nic address. A mac address is used to identify the only computer. In other words, a computer has only one mac address.

This is also the method that many programs use to identify independent users. However, the mac address is divided into the physical mac and the mac address of the driver layer.

The mac address of the driver layer can be modified. The mac is the same as the mac address of the physical network card before it is modified.

The program reading mac can not directly obtain the physical mac, but the mac of the driver layer. So we can achieve our goal by changing the driver layer mac.

How to modify a mac address

You can modify the mac address by changing the registry, or you can download the existing mac address modifier

1. Download the tmac program. Download address is http://www.technitium.com/tmac/index.html

three. PHP long-time operation mode

The php program ends automatically after running for a period of time. In order to keep php running, you can modify the parameter max_execute_time. Php.ini.

Modify max_execution_time = 0
