子域不解析為 IP

我創建了一個子域http://themes.ibrogram.com，它似乎不起作用，但http://ibrogram.com/themes確實有效。

我使用 A 記錄多年來一直有這個問題，但似乎無法弄清楚如何解決它。

有任何想法嗎？

您需要添加具有以下 A 記錄的區域文件條目：

themes    3600    IN  A   199.38.116.24

您可以通過鍵入來驗證它是否已解決

dig themes.ibrogram.com

請注意，您仍然需要確保您的 Web 伺服器設置為基於命名的託管。假設它是 Apache，它將類似於：

NameVirtualHost *:80

<VirtualHost *:80>
ServerName themes.ibrogram.com
DocumentRoot /path/to/themes
</VirtualHost>
