linux下nslookup操作实例,查找域名的a记录、mx记录、cname记录、ns记录

basic shang 343浏览 0评论

说明:
以下是在linux下的操作实例,win下的nslookup操作实例请看附录1:win下的nslookup操作实例
nslookup有2种模式,交互模式、非交互模式

实例:
一、以下实例为nslookup非交互模式下操作
实例1:查找域名A记录

# nslookup coolnull.com
Server:		100.100.2.138
Address:	100.100.2.138#53

Non-authoritative answer:
Name:	coolnull.com
Address: 120.24.240.59

 
查找域名A记录
上面下面都一样,只是查询的时候多了-query=a,因为nslookup默认就是查询a记录,所以不写也一样。

# nslookup -query=a coolnull.com
Server:		100.100.2.138
Address:	100.100.2.138#53

Non-authoritative answer:
Name:	coolnull.com
Address: 120.24.240.59   ###这是解析出来coolnull.com对应的ip地址

 
实例2:查询域名A记录,指定dns服务器,通过在域名后指定dns服务器地址

# nslookup coolnull.com 8.8.8.8
Server:		8.8.8.8
Address:	8.8.8.8#53

Non-authoritative answer:
Name:	coolnull.com
Address: 120.24.240.59

 
实例3:查找MX记录

# nslookup -query=mx coolnull.com
Server:		100.100.2.138
Address:	100.100.2.138#53

Non-authoritative answer:
coolnull.com	mail exchanger = 10 mxbiz2.qq.com.     ###域名mx记录为mxbiz1.qq.com.、mxbiz2.qq.com.有用过qq免费域名邮箱的应该熟悉,当然还有mxdomain.qq.com.这个
coolnull.com	mail exchanger = 5 mxbiz1.qq.com.

mxbiz1.qq.com	internet address = 112.90.78.144
mxbiz2.qq.com	internet address = 112.90.78.144
mxbiz2.qq.com	internet address = 163.177.89.176

f1g1ns1.dnspod.net	internet address = 182.140.167.166
f1g1ns1.dnspod.net	internet address = 14.215.150.17
f1g1ns2.dnspod.net	internet address = 52.220.136.67
f1g1ns2.dnspod.net	internet address = 61.129.8.159
f1g1ns2.dnspod.net	internet address = 101.226.220.16
f1g1ns2.dnspod.net	internet address = 121.51.128.164
f1g1ns2.dnspod.net	internet address = 182.140.167.188

 
实例4:查找域名CNAME记录

# nslookup -query=cname www.baidu.com
Server:		100.100.2.138
Address:	100.100.2.138#53

Non-authoritative answer:
www.baidu.com	canonical name = www.a.shifen.com.    ###可以看到www.baidu.com是cname到www.a.shifen.com

baidu.com	nameserver = ns3.baidu.com.
baidu.com	nameserver = ns7.baidu.com.
baidu.com	nameserver = ns2.baidu.com.
baidu.com	nameserver = dns.baidu.com.
baidu.com	nameserver = ns4.baidu.com.
dns.baidu.com	internet address = 202.108.22.220
ns2.baidu.com	internet address = 61.135.165.235
ns3.baidu.com	internet address = 220.181.37.10
ns4.baidu.com	internet address = 220.181.38.10
ns7.baidu.com	internet address = 180.76.76.92

 
实例5:查看域名NS(nameserver)记录

# nslookup -query=ns coolnull.com
Server:		100.100.2.138
Address:	100.100.2.138#53

Non-authoritative answer:
coolnull.com	nameserver = f1g1ns1.dnspod.net.    ###这边可以看到coolnull.com的ns地址为f1g1ns1.dnspod.net.和f1g1ns2.dnspod.net.,这是dnspod免费域名服务器的域名地址。
coolnull.com	nameserver = f1g1ns2.dnspod.net.

f1g1ns1.dnspod.net	internet address = 180.163.19.15    ####dnspod免费域名服务器的域名对应的ip地址
f1g1ns1.dnspod.net	internet address = 182.140.167.166
f1g1ns1.dnspod.net	internet address = 14.215.150.17
f1g1ns1.dnspod.net	internet address = 58.247.212.36
f1g1ns1.dnspod.net	internet address = 115.236.151.191
f1g1ns2.dnspod.net	internet address = 61.129.8.159
f1g1ns2.dnspod.net	internet address = 101.226.220.16
f1g1ns2.dnspod.net	internet address = 121.51.128.164
f1g1ns2.dnspod.net	internet address = 182.140.167.188
f1g1ns2.dnspod.net	internet address = 52.220.136.67

 
二、以下实例为nslookup交互模式下操作
要进入nslooku交互模式只需要在命令行输入nslookup即可,更多参数可以查看这篇nslookup – man手册
实例1:查找域名A记录

# nslookup
> set query=a
> coolnull.com
Server:		100.100.2.138
Address:	100.100.2.138#53

Non-authoritative answer:
Name:	coolnull.com
Address: 120.24.240.59    ###这是解析出来coolnull.com对应的ip地址

 
实例2:查找MX记录

# nslookup
> set query=mx    ###set query=mx后,可以直接输入其它域名查找该域名的mx记录。不需要再重复set query=mx;当然如果要查找其它记录,如a记录,还是需要再set query=a
> coolnull.com
Server:		100.100.2.138
Address:	100.100.2.138#53

Non-authoritative answer:
coolnull.com	mail exchanger = 5 mxbiz1.qq.com.     ###域名mx记录为mxbiz1.qq.com.、mxbiz2.qq.com.
coolnull.com	mail exchanger = 10 mxbiz2.qq.com.
