Azure 应用服务 - 出站 IP 地址与其他出站 IP 地址

Question

Azure 应用服务有 2 种类型的出站 IP 地址:

1. 出站 IP 地址:
2. 其他出站 IP 地址:

我想知道从白名单的角度来看，我需要在防火墙中使用哪个类别？

Answer 1

据我所知，您应该将其他出站 IP 地址列入白名单:

An App Service app runs in an App Service plan, and App Service plansare deployed into one of the deployment units in the Azureinfrastructure (internally called a webspace). Each deployment unit isassigned up to five virtual IP addresses, which includes one publicinbound IP address and four outbound IP addresses. All App Serviceplans in the same deployment unit, and app instances that run in them,share the same set of virtual IP addresses. For an App ServiceEnvironment (an App Service plan in Isolated tier), the App Serviceplan is the deployment unit itself, so the virtual IP addresses arededicated to it as a result.

Because you're not allowed to move an App Service plan betweendeployment units, the virtual IP addresses assigned to your appusually remain the same, but there are exceptions.

因此，对于某些异常(exception)情况，例如您在层之间扩展应用程序，四个出站 IP 地址中的一个或多个可能会发生变化(其中包括一些其他出站 IP 地址)请参阅:When outbound IPs change
