为什么找不到我的根域的服务器 DNS 地址？

为什么找不到我的根域的服务器 DNS 地址？

我（以为我）按照说明将自定义域映射到 Azure 上的 Web 应用程序这里。我使用 Namecheap 为“@”根主机创建了 A 记录和 TXT 记录，还为“www”子域创建了 A 记录和 TXT 记录。只有“www”子域为页面提供服务。我可以同时为两者创建 A 记录和 TXT 记录吗？我还为“www”子域设置了 CNAME。

Azure 对域和子域的验证都已完成，但页面仅提供给“www”子域。

我应该设置重定向吗，比如rankmemestash.com->www.rankmemestash.com，而是？我确实尝试过这个，但遇到了同样的错误。

对我来说，你的裸域名如下所示：

;rankmemestash.com.     IN  ANY
rankmemestash.com.  1799    IN  A   162.255.119.248

这两条A记录将导致轮询 DNS后续请求可能会解析到这两个不同的 IP 地址。这也许可以解释为什么http://rankmemestash.com如果其中只有一个是活动的 Web 服务器，那么有时会成功，有时会失败。相比之下：记录www仅指向：168.62.180.173
