新网别名解析存在巨大缺陷

因为域名是三线空间,我想把这个域名解析到智能域名解析服务器,通过这个别名服务器可以智能解析用户到对应的三个ip,新网别名设置好后,发现许多DNS刷新不同步,等了2天,还是无法正确解析别名,直接把WWW解析到A记录则完全正常,10分钟后美国DNS刷新正常,解析别名就是有问题

C:Documents and Settingsheadwind>nslookup www.zgwww.net 61.134.35.20
Server:  dns.hyinfo.net
Address:  61.134.35.20

DNS request timed out.
    timeout was 2 seconds.
*** Request to dns.hyinfo.net timed-out

某地方DNS查不到解析结果

C:Documents and Settingsheadwind>nslookup zgwww.net 61.134.35.20
Server:  dns.hyinfo.net
Address:  61.134.35.20

Name:    zgwww.net
Address:  58.66.176.115

根域名解析正常

C:Documents and Settingsheadwind>nslookup www.zgwww.net 61.134.35.20
Server:  dns.hyinfo.net
Address:  61.134.35.20

*** dns.hyinfo.net can(i)t find www.zgwww.net: Non-existent domain

WWW域名显然无法解析,改用广东DNS

C:Documents and Settingsheadwind>nslookup www.zgwww.net 202.96.128.86
Server:  cache-a.guangzhou.gd.cn
Address:  202.96.128.86

Non-authoritative answer:
Name:    NS1.DNS567.COM
Address:  58.66.176.115
Aliases:  www.zgwww.net

其结果是正常的,使用国外DNS

C:Documents and Settingsheadwind>nslookup www.zgwww.net 137.65.1.1
Server:  ns.novell.com
Address:  137.65.1.1

DNS request timed out.
    timeout was 2 seconds.
Non-authoritative answer:
Name:     NS1.DNS567.COM
Address:  58.66.176.115
Aliases:  www.zgwww.net

结果也是正常的

 

直接用新网的服务器

C:Documents and Settingsheadwind>nslookup www.zgwww.net 210.51.171.209
*** Can(i)t find server name for address 210.51.171.209: Non-existent domain
Server:  UnKnown
Address:  210.51.171.209

*** UnKnown can(i)t find www.zgwww.net: Non-existent domain

C:Documents and Settingsheadwind>nslookup www.zgwww.net ns.xinnetdns.com
Server:  ns.xinnetdns.com
Address:  210.51.170.66

*** ns.xinnetdns.com can(i)t find www.zgwww.net: Non-existent domain

C:Documents and Settingsheadwind>nslookup -qt=cname www.zgwww.net ns.xinnetd.com
DNS request timed out.
    timeout was 2 seconds.
*** Can(i)t find server name for address 210.51.170.66: Timed out
Server:  UnKnown
Address:  210.51.170.66

www.zgwww.net   canonical name =  NS1.DNS567.COM

原来新网这里有问题,运气好解析到好的域名服务器就正常了,运气不好解析到不好的服务器上就超时,其他服务器就无法响应,直接导致域名解析失败

最后得出结果,新网A记解析录比CNAME别名解析稳定,如果要通过只能解析,必须把NS解析权交给非新网DNS
