  1. host 命令：

    通常格式：
    host 域名
    host -a 域名 shell

    經常使用選項：
    -a：至關於"-v -t any"。
    -t type：指定要查詢的記錄類型。默認查詢A、AAAA、MX記錄。
    -v：詳細方式輸出。 windows

  2. dig 命令：

    通常格式：
    dig [@global-server] [domain] [q-type] [q-class] {q-opt} {d-opt} 服務器

    參數說明：
    @global-server：默認是以/etc/resolv.conf做爲DNS查詢的主機，這裏能夠填入其它DNS主機IP。
    domain：要查詢的域名。
    q-type：查詢記錄的類型，例如a、any、mx、ns、soa、hinfo、axfr、txt等，默認查詢a。
    q-class：查詢的類別，至關於nslookup中的set class。默認值爲in（Internet）。
    q-opt：查詢選項，能夠有好幾種方式，好比：-f file爲經過批處理文件解析多個地址；-p port指定另外一個端口（缺省的DNS端口爲53），等等。
    d-opt：dig特有的選項。使用時要在參數前加上一個「+」號。 dom

    d-opt經常使用選項：
    +vc：使用TCP協議查詢。
    +time=###：設置超時時間。
    +trace：從根域開始跟蹤查詢結果。 tcp

    最基本的使用方式就是
dig www.baidu.com
即查詢域名的A記錄，查詢的dns服務器將採用系統配置的服務器，即/etc/resovle.conf 中的。
若是要查詢其餘類型的記錄，好比MX，CNAME，NS，PTR等，只需將類型加在命令後面便可
dig www.baidu.com mx
dig www.baidu.com ns
此外，若是你是一個系統管理員，部署好了一臺dns服務器以後想對它進行解析測試，就必需要顯式指定待測試的dns服務器地址了，例如
dig @202.106.0.20 www.baidu.com a
默認狀況下dig將採用udp協議進行查詢，若是要採用tcp方式，能夠加上 +tcp參數
dig www.baidu.com a +tcp
另一個重要的功能是+trace參數，使用這個參數以後將顯示從根域逐級查詢的過程
dig www.oolec.com a +trace
    [root@BJ-IDC-NTP-002 ~]# dig +trace www.163.com

; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.30.rc1.el6_6.3 <<>> +trace www.163.com

    nslookup命令使用頻率比dig要高，多是由於windows上沒有dig命令吧。 測試

    通常格式：
    nslookup [-option] [name | -] [server] .net

    參數說明：
    option：表示一些選項。這些選項能夠經過set命令設置修改。
    name：表示查詢的域名。
    server：能夠指定DNS主機IP。 debug

    set命令說明：
    set all：打印當前的選項值。
    set calss=value：設置查詢的類型，通常狀況下爲Internet。
    set debug：設置調試模式。
    set d2：設置詳細調試模式。
    set domin=name：設置默認的域名。
    set search：
    set port=value：設置DNS端口。
    set querytype=value：改變查詢的信息的類型。默認的類型爲A紀錄。
    set type=value：和set querytype同樣。
    set recurse：設置查詢類型爲遞歸；若爲set norecurse，查詢類型爲跌代；缺省爲前者。
    set retry=number：設置重試的次數。
    set timeout=number：設置等待應答的限制時間（單位爲秒），超出即爲超時，若是還能夠重試，就會將長超時值加倍，從新查詢。
    set vc：經過tcp方式查詢。
    set fail： 調試

    具體說明能夠查看man手冊。 code
