检测你一下你DNS方面的知识

发布时间:2005-06-05 00:17:48来源:红联作者:风雨无阻
转:哈哈,这是我在网上搜索到的很不错!看来给大家看看,大家来答答吧。这些问题看上去都是很简单的,其实并不是这样的。我一周以后公布答案!!

如果你觉得自己关于dns还算了解的话,请试着回答以下几个问题:
1、zone数据文件中的@代表什么?IN 代表什么?
2、为什么有时dig可以通过某个nameserver查询,而nslookup却告知无法找到nameserver?
3、什么是lame server?
4、你会做子网段不是8位8位时的IP地址反向解析吗?
5、Internet上是正向解析多还是反向解析多?
6、将zone数据传输功能关闭,你的域内主机就一定安全吗?
