dns查询问题

我想查询dns server上的信息，本地linux上没有启动dns server,nslookup 命令查询没有要求一定要在本地启动dns 吧。可是运行时候出现下列问题，是何原因？
bash# nslookup
Note:  nslookup is deprecated and may be removed from future releases.
Consider using the `dig' or `host' programs instead.  Run nslookup with
the `-sil[ent]' option to prevent this message from appearing.
