自动分配范围 - 创建 Apigee 实例时，允许 Apigee 从分配给 Google 的较大范围分配任何可用的非重叠范围。每次重新创建实例时，系统都会自动分配 IP 地址范围。在这种情况下，新实例可能会使用新的 IP 地址范围（如果有），并且不与其他产品或服务重叠。
指定 IP 范围 - 您可以指定 Apigee 将使用的 IP 范围。此 IP 地址范围必须来自与 Apigee 对等互连的非重叠范围。如果您要为多个 Cloud 产品（例如 Cloud SQL、Cloud Memorystore、Apigee 等）分配更大的 IP 地址范围，并且还能够为每个产品指定实际的 IP 地址范围，则此选项非常有用。此范围可以是非 RFC 1918 IP 地址范围，只要该范围不是以非公开方式使用的公共 IP 地址（PUPI 地址）。.
