如何确保私有 DNS 区域正在解析给定的私有 IP？
How to make sure a Private DNS zone is resolving a given private ip?
这里的用例场景是私有 DNS 解析一个内部 IP 作为 API 管理器的默认网关 - APIM.
在 APIM 前面，有一个应用程序网关，其后端池以私有 DNS 为目标。
我可以看到后端健康状态是 unknown，它可能与 FQDN 有关 - 与内部 Ip 关联，未被解析，但我如何确保它是实际的有问题吗？
- 我宁愿不必创建整个 VM 只是为了按名称 ping 它。
您可以尝试以下任一方法来确保私有 DNS 区域正在解析给定的私有 IP。
Workaround 1:
- Create an Azure VNet with a DNS private zone like private.test.com.
- Create a VM and a VPN gateway on that VNet. Enable VNet integration.
- with my Azure web app service.
Workaround 2:
- Deploy new Azure Private DNS Zones
in your Azure environment part of private endpoint deployment.
(Default option)
- Use existing Azure Private DNS Zones.
Use this option if you using a private endpoint in a hub-and-spoke
model from a different subscription or even within the same
subscription.
- Use your own DNS Servers
if you do not use DNS forwarders and instead you manage A records
directly in your on-premises DNS servers.
