标题: 帮忙看看dns解析不了的问题
新网注册的，想用自己的dns来解析。设置了，发现有问题，看下面：

aaaa@bbbb:~$ dig cutedns.org

; <<>> DiG 9.6.1-P1 <<>> cutedns.org
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 34019

;; WHEN: Tue Jul 27 14:28:23 2010
;; MSG SIZE  rcvd: 29

这里看是解析不了。

从上面看，我的dns已经设置上了。就是220.194.52.131和210.51.9.205

aaaa@bbbb:~$ dig @220.194.52.131 cutedns.org

权威服务器回应的status是SERVFAIL，递归服务器就不会给出A记录了。检查一下权威服务器的设置吧。

谢楼上。

在ns1.cutedns.org、ns2.cutedns.org上添加

@    IN    NS ns1.cutedns.org.
@    IN    NS ns2.cutedns.org.

ns1 IN    A    ns1_ip
ns2 IN    A    ns2_ip

我上面有ns1和ns2的NS记录。修改了，但是查询还是这个SERVERFAIL，是缓存么？

$ dig @220.194.52.131 -t ns cutedns.org

很奇怪，实际上我设置了ns1和ns2的。我设置的不对吗
