011-nslookup的用法

若是主機多， 要肯定這些主機有沒有DNS解析，nslookup簡單實用

[chkusr@CNSZ041791 ~]$ nslookup cnsz181080
;; Got SERVFAIL reply from 10.11.86.15, trying next server
Server:         10.37.90.15
Address:        10.37.90.15#53

** server can't find cnsz181080: SERVFAIL
沒有解析

[chkusr@CNSZ041791 ~]$ nslookup cnsz131303
Server:         10.11.86.15
