我注册的web000的免费域名，相关信息如下：

Access your website at http://luofeiyu.comeze.com
Access your website with www. http://www.luofeiyu.comeze.com
Website IP address 31.170.160.111
Server name server47.000webhost.com

我在浏览器中，输入http://luofeiyu.comeze.com ，可以得到


为何无法获得它的ip地址？这个网站有域名，但是没有ip地址？既然这样，如何被解析到的？

ping luofeiyu.comeze.com/
ping: unknown host luofeiyu.comeze.com/
ping http://luofeiyu.comeze.com/
ping: unknown host http://luofeiyu.comeze.com/
ping http://www.luofeiyu.comeze.com/
ping: unknown host http://www.luofeiyu.comeze.com/

dig luofeiyu.comeze.com
... 省略
luofeiyu.comeze.com. 599 IN A 31.170.162.23
... 省略

表示 你在 DNS 的 A 記錄是 31.170.162.23
表示 http://luofeiyu.comeze.com 會 解析成 http://31.170.162.23

試試
ping luofeiyu.comeze.com
ping 31.170.162.23
ping 31.170.160.111

如果你剛剛建立/修改這個 A 記錄
可能立刻生效
可能要稍候才生效
一般需要等待時間不會超過 24 小時

有的網站設定對於 ping 等等指令 不回應
你可以寫個電子郵件向 web000 求證

當你的 IP 已經改變時 需要立刻到 DNS 修改 A 記錄
使用 DDNS Script file 可以自動完成這件事

補充

剛剛試了一下
