摘　　要：当我们在浏览器里面输入网址时,DNS 服务器会自动把它解析为 IP 地址,浏览器实际上查找的是 IP 地址而不是网址。那么 IP 地址是如何转换为 MAC 地址的呢?在局域网中,这是通过 ARP 协议来完成的。ARP 协议对网络安全具有重要的意义。通过伪造 IP 地址和 MAC 地址实现 ARP 欺骗,能够在网络中产生大量的 ARP 通信量使网络阻塞。所以通过本文将使我们更加深入地理解 ARP 协议的攻击原理及防御方法。When we input the website in the browser,the DNS server will analyze it will be the IP address automatically,what the browser will search Hill be the IP address,but will not be the website in fact.How does the IP address transform to the MAC address?In local area network,this is completes through the ARP protocol.The ARP protocol has the vital significance to the network security.Realize the ARP forge through the forge IP address and the MAC address,can have the massive ARP communication load in the network to cause the network congestion.Therefore will make us through this article to understand the ARP protocol thoroughly the attack principle and the defensive method.
