防止arp欺骗，保护网络的安全。比较好的学习arp的源代码。

经测试可有效应对网络执法官、netcut等工具，对于网络执法官等造的IP冲突，可不于理睬，把提示窗口拖到不碍眼的地方（win2000)即可，不影响上网。可以显示攻击的MAC地址。

支持连续防护和仅需要时防护两种模式。程序退出时自动保存设置（网卡选择和防护模式），自动恢复本机环境,自动检测网关变化，方便笔记本使用。版权归作者所有！-prevent fraud, the protection of the network security. Arp relatively good learning source. After the tests will be an effective response network marshals, netcut tools such as the network of agents and other IP create conflict, may, in turn, prompt window until not unsightly places (WIN2000) will not affect the Internet. The attack shows the MAC address. Continuous protection and support only when necessary protection in two modes. Withdraw from the process automatically preserve settings (network interface card options and protective mode), automatic resumption of the machine, auto-detect Gateway changes Notebook convenient to use.
