DNS问题请教!

各位大虾,

请问RH7.1中的ndc在哪里??(每次修改了***.conf,没办法只能重新启动)

我用nslookup后出现一大串信息:
note:nslookup is a deprecated and maybe removed from feture released,consider using the 'dig' or 'host'..........
>
然后我输入193.9.201.15后出现
server:193.9.201.15
address:193.9.201.15#53

15.201.9.193.in-addr.arpa name:dhl.cims.
上面的#53是何意,为何没有
default server:dhl.cims
address:193.9.201.15

193.9.201.15 name:dhl.cims

同时发现启动日志文件提示
loading configuration from'/etc/named.conf'
the default for the 'auth-nxdomain' option is now 'no'

请各位指教!

谢谢了
