要查詢DNS伺服器的版本，
可使用nslookup或dig指令來查詢：

#nslookup -q=txt -class=chaos version.bind xxx.xxx.xxx.xxx
或
#dig txt chaos version.bind @xxx.xxx.xxx.xxx

其中xxx.xxx.xxx.xxx是DNS伺服器的IP位址。

 

例1：
# nslookup -q=txt -class=chaos version.bind xxx.xxx.xxx.xxx
;; Warning: query response not set
;; Warning: Message parser reports malformed message packet.
Server: xxx.xxx.xxx.xxx
Address: xxx.xxx.xxx.xxx#53

version.bind text = “Microsoft DNS 6.1.7601 (1DB14556)”

 

例2：
# nslookup -q=txt -class=chaos version.bind yyy.yyy.yyy.yyy
Server: yyy.yyy.yyy.yyy
Address: yyy.yyy.yyy.yyy#53

version.bind text = “9.3.6-P1-RedHat-9.3.6-4.P1.el5_4.2”

 

例3：
# nslookup -q=txt -class=chaos version.bind zzz.zzz.zzz.zzz
Server: zzz.zzz.zzz.zzz
Address: zzz.zzz.zzz.zzz#53

version.bind text = “9.3.2”

 

例4：
# dig txt chaos version.bind @xxx.xxx.xxx.xxx

; <<>> DiG 9.3.6-P1-RedHat-9.3.6-20.P1.el5 <<>> txt chaos version.bind @xxx.xxx.xxx.xxx
