我要评论nslookup -qe=mx ebadu.net
正确指示:
c:\documents and settings\administrator>nslookup -qe=mx ebadu.net
server: ns.ahhfptt.net.cn
address: 202.102.192.68
dns request timed out.
timeout was 2 seconds.
non-authoritative answer:
ebadu.net mx preference = 0, mail exchanger = mail.ebadu.net
ebadu.net nameserver = ns2.dns.com.cn
ebadu.net nameserver = ns1.dns.com.cn
mail.ebadu.net internet address = 222.186.12.16
ns1.dns.com.cn internet address = 122.70.138.5
ns1.dns.com.cn internet address = 122.70.138.6
ns1.dns.com.cn internet address = 124.42.122.8
ns1.dns.com.cn internet address = 124.42.122.9
ns2.dns.com.cn internet address = 124.42.122.5
ns2.dns.com.cn internet address = 124.42.122.6
ns2.dns.com.cn internet address = 122.70.138.8
ns2.dns.com.cn internet address = 122.70.138.9
见到ns记录显示了ip 即为通畅状态
nslookup -qe=mx ebadu.com
c:\documents and settings\administrator>nslookup -qe=mx ebadu.com
server: ns.ahhfptt.net.cn
address: 202.102.192.68
dns request timed out.
timeout was 2 seconds.
non-authoritative answer:
ebadu.com canonical name = www.center.ebadu.net
ebadu.net
primary name server = ns2.dns.com.cn
responsible mail addr = root.ns2.dns.com.cn
serial = 2008061113
refresh = 3600 (1 hour)
retry = 3600 (1 hour)
expire = 68400 (19 hours)
default ttl = 180 (3 mins)
反馈不回nsip记录.即为不通状态!
检测反解析是否成功
nslookup –qt=ptr 61.191.191.182
返回信息如下：
c:\documents and settings\user>nslookup –qt=ptr 61.192.56.23
server: mx.diyway.net
address: 61.192.56.23
说明这个ip的反解析就是成功了。
