怎么查域名反向解析是否成功
答朋友:
比如您mail服务器固定IP是218.5.x.x,那么可以用nslookup来查反向解析有没有成功。
C:\Documents and Settings\Administrator>nslookup 218.5.xxx.xxx
Server: FJ-DNS.fz.fj.cn
Address: 218.85.157.99
Name: xxxxx.com
Address: 218.5.x.x
如果没做反向的会得到以下结果
C:\Documents and Settings\Administrator>nslookup 218.5.xx.xx
Server: FJ-DNS.fz.fj.cn
Address: 218.85.157.99
*** FJ-DNS.fz.fj.cn can't find 218.5.79.30: Non-existent domain
