本來好像都正常，但之前試著套Cloudflare服務失敗後
又把Cloudflare服務停掉，改回用域名商Name.com的DNS服務
並且設定回主機商Hostgator的nameservers
再把.htaccess檔案還原回去，算是又能正常連線了
可是使用http://www.intodns.com 測試後
列出了以下幾項錯誤：
1.(紅驚嘆號)Recursive Queries
I could use the nameservers listed below to performe recursive queries.
It may be that I am wrong but the chances of that are low.
You should not have nameservers that allow recursive queries
as this will allow almost anyone to use your nameservers and
can cause problems.
Problem record(s) are:
192.185.5.103
192.185.5.102
2.(黃驚嘆號)Different subnets
WARNING: Not all of your nameservers are in different subnets
3.(黃驚嘆號)Different autonomous systems
WARNING: Single point of failure
4.(黃驚嘆號)SOA EXPIRE
Your SOA EXPIRE number is: 3600000. That is NOT OK
5.(紅驚嘆號)Reverse MX A records (PTR)
ERROR: No reverse DNS (PTR) entries.
The problem MX records are:
237.16.185.192.in-addr.arpa -> no reverse (PTR) detected
You should contact your ISP and ask him to add a PTR record for your ips
剛開始建設階段，這方面的功課還需要多練習
希望能請強者指點，謝謝
