In the previous<br />example, packets sent to 10.0.0.1 - 10.0.0.255 would use the 10/24 route,<br />since it is more specific, while packets sent to 10.0.1.1 - 10.0.1.255 would use<br />the 10/23 route, since they do not match the 10/24 route but do match the<br />10/23 route.

在这个例子中 目的地址相同 掩码不同, 最精确适合的路由（线路，表）会被选择<br />前一个例子中, 发往10.0.0.1 - 10.0.0.255 的packets(包)将会到应用10/24 路由，因为它是更精确的<br />而发往10.0.1.1 - 10.0.1.255 的packets(包)将会到采用10/23路由，因为（发往这个子网的路由）10/23路由是更精确的<br /> <!--emo&:awkard:--><img src='style_emoticons/default/awkard.gif' border='0' style='vertical-align:middle' alt='awkard.gif' /><!--endemo--> 胡乱说的。<br /><br />10.0.0.1？这不是未注册的，可供内网用的吗
