我的网络管理员为thedigitalteacher.com创建了一个DNS记录,其中应包括指向5.10.124.142的域根目录的A记录,这确实是我使用内部名称服务器时得到的响应。
但是,8.8.8.8上的Google名称服务器经常(但并非总是)无法解析名称,导致这种胡说八道:
ahrcsdca01115:triangle-app bodeng$ nslookup
> server 8.8.8.8
Default server: 8.8.8.8
Address: 8.8.8.8#53
> thedigitalteacher.com
Server: 8.8.8.8
Address: 8.8.8.8#53
** server can't find thedigitalteacher.com: NXDOMAIN
> set querytype=any
> thedigitalteacher.com
Server: 8.8.8.8
Address: 8.8.8.8#53
Non-authoritative answer:
Name: thedigitalteacher.com
Address: 5.10.124.142
thedigitalteacher.com nameserver = ns0.dcdns.net.
thedigitalteacher.com nameserver = ns1.dcdns.net.
thedigitalteacher.com nameserver = ns2.dcdns.net.
thedigitalteacher.com nameserver = ns3.dcdns.net.
thedigitalteacher.com
origin = ns0.dcdns.net
mail addr = domains.ucles.org.uk
serial = 22
refresh = 900
retry = 600
expire = 86400
minimum = 3600
thedigitalteacher.com mail exchanger = 10 66.96.140.160.
Authoritative answers can be found from:
> set querytype=a
> thedigitalteacher.com
Server: 8.8.8.8
Address: 8.8.8.8#53
Non-authoritative answer:
Name: thedigitalteacher.com
Address: 5.10.124.142
我如何找出该域出了什么问题?
