以前上学不知道是老师讲了还是自己没记住,今天百度下,知道怎么查了,还是通过nslookup命令查询,
s:\>nslookup
DNS request timed out.
timeout was 2 seconds.
*** Can't find server name for address 192.169.1.1: Timed out

*** Can't find server name for address 192.169.1.1: Timed out

Non-authoritative answer:
i-lemon.cn MX preference = 0, mail exchanger = 1443256101.pamx1.hotmail.com
i-lemon.cn nameserver = ns1.beijingidc.com
i-lemon.cn nameserver = ns4.beijingidc.com
ns1.beijingidc.com internet address = 210.51.7.166
ns4.beijingidc.com internet address = 114.111.162.114
顺便说下:
什么是MX记录?
MX(Mail Exchanger)记录是邮件交换记录,它指向一个邮件服务器,用于电子邮件系统发邮件时根据 收信人的地址后缀来定位邮件服务器。例如,当Internet上的某用户要发一封信给 user@mydomain.com 时,该用户的邮件系统通过DNS查找mydomain.com这个域名的MX记录,如果MX记录存在, 用户计算机就将邮件发送到MX记录所指定的邮件服务器上。
如果MX记录不存在就会出现一下信息:
> set type=mx
> l-shine.com
Server: gjjdial.bta.net.cn
Address: 202.106.195.68
*** gjjdial.bta.net.cn can't find l-shine.com: Non-existent domain
