1.4 代理ARP

代理ARP被路由器作为向主机表明自身可用的一种手段。

这是在思科的网站上看到关于代理ARP的介绍（解释的非常清楚）

Proxy ARP is the technique in which one host, usually a router, answers ARP requests intended for another machine. By "faking" its identity, the router accepts responsibility for routing packets to the "real" destination. Proxy ARP can help machines on a subnet reach remote subnets without the need to configure routing or a default gateway. Proxy ARP is defined in RFC 1027
