摘要
介绍了一种基于GSM网络传输服务器动态IP地址的模块。详细阐述了设计思路并制作了应用模块。服务器通过拨号方式登陆网络,获取动态IP地址,通过发送模块将IP地址传输到配有接收模块的客户终端,节约了成本,避免了租用专线和固定IP地址昂贵的费用;同时,减少了服务器使用静态IP容易遭受网络攻击的问题,使整个服务器系统的安全性得到提高,在企业得到应用。
A module based on GSM net transmission servers dynamic IP addresses is presented. The design is expounded with details and the application modules are manufactured. Servers surf the Internet through dial-up and get dynamic IP addresses that can be transmitted to the customer terminals with receiver modules, by the sending modules. This method avoids the high cost of hiring dedicated lines and fixed IP address, so that it can cut costs. At the same time, the problem that the server using static IP can be attacked easily is solved. All the security of the server system is improved, in addition, receiving applications in the enterprise.
