DNS查询工具：host、nslookup、dig
作者：zhanhailiang 日期：2014-11-01
1. host
- host提供域名到IP地址的双向解析；
- host默认通过/etc/resolv.conf读取Name Server来解析，除非提供可选參数server。
- -a參数相当于进行ANY查询。
[root@~]# host pic1.vip.com
pic1.vip.com is an alias for pic1.vip.com.wscdns.com.
pic1.vip.com.wscdns.com is an alias for vipshop.xdwscache.glb0.lxdns.com.
vipshop.xdwscache.glb0.lxdns.com has address 111.206.217.105
vipshop.xdwscache.glb0.lxdns.com has address 125.39.1.138
vipshop.xdwscache.glb0.lxdns.com has address 218.59.186.76
vipshop.xdwscache.glb0.lxdns.com has address 111.206.169.23
[root@~]# host pic1.vip.com 8.8.8.8

2. nslookup
- nslookup提供交互式和非交互式两种查询方式；
[root@~]# nslookup

Server: 10.202.72.116
Address: 10.202.72.116#53
Non-authoritative answer:
pic1.vip.com canonical name = pic1.vip.com.wscdns.com.
pic1.vip.com.wscdns.com canonical name = vipshop.xdwscache.glb0.lxdns.com.
Name: vipshop.xdwscache.glb0.lxdns.com
Address: 125.39.1.138
Name: vipshop.xdwscache.glb0.lxdns.com
Address: 218.59.186.76

Address: 111.206.169.23
Name: vipshop.xdwscache.glb0.lxdns.com
Address: 111.206.217.105
> exit
[root@~]# nslookup pic1.vip.com
Server: 10.202.72.116
Address: 10.202.72.116#53
Non-authoritative answer:

3. dig

- dig是一个询问DNS域名服务的灵活工具，提供了来自被要求的，返回名称服务DNS的查询和显示的答案。大多数DNS管理员使用dig来排除DNS故障和问题；
- 其基本用法：dig [@server] name [type]。
1. 普通使用方法：dig pic1.vip.com
[root@~]# dig pic1.vip.com

2. 进行ANY查询：
[root@~]# dig vip.com ANY
; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.23.rc1.el6_5.1 <<>> vip.com ANY
;; global options: +cmd

3. 使用+trace參数，追踪查询过程：
[root@~]# dig pic1.vip.com +trace
; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.23.rc1.el6_5.1 <<>> pic1.vip.com +trace

4. 指定name server，使用+trace參数，能够看到第一步是通过指定的@server查询根服务器：
[root@~]# dig @8.8.8.8 pic1.vip.com +trace
; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.23.rc1.el6_5.1 <<>> @8.8.8.8 pic1.vip.com +trace
