Hi,

Firstly the DNS serveres for that domain is not mastered by me.
I got the NS dig info as below.
You can see, if I specify another public DNS (211.66.80.161), the results can be fetched. If I don't specify a DNS (use the default one 202.96.128.143 of my ISP), dig gets nothing.
So I'm really confused on their configure.
Please help again, thanks~
