奇怪的DNS问题，虚拟机下可以，真实的环境却出错，希望大家帮助下

http://linux.chinaunix.net/bbs/thread-1094816-1-1.html

我按照上面的文章搭建DNS，当我在虚拟机下作的时候是正确的，可以显示的服务器和IP的，当我在真实环境下作的时候，显示的却是错误的，
[root@rhel5 named]# nslookup

 我也是第一次弄DNS，不知道是啥原因，我把我的配置文件铁出来，大家给个建议吧，配置文件我和虚拟机下的都是按照上面的网址的文字搭建的，却欻现不一样的问题，实在有点郁闷，我把配置文件铁出来
gedit world7th.cn.zone

以上就是我所以的配置文件，我在虚拟机下可以成功的，在真实的环境下却不行，希望大虾给指点下，到底是那里出来问题，我是ADSL的用户，实验是可以上网，我的网卡的ip是192.168.1.123，希望帮帮我吧。
