--- Title: Configure subscription CIDR allow list alwaysopen: false categories: - docs - operate - rc description: The CIDR allow list permits traffic between a range of IP addresses and the Redis Cloud VPC. linkTitle: Subscription CIDR allow list weight: $weight aliases: - /operate/rc/how-to/view-edit-cloud-account/subscription-whitelist - /operate/rc/cloud-accounts/subscription-whitelist - /operate/rc/cloud-integrations/aws-cloud-accounts/subscription-whitelist --- The [CIDR](https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing) [allow list](https://en.wikipedia.org/wiki/Whitelist) lets you restrict traffic to your Redis Cloud database. When you configure an allow list, only the [IP addresses](https://en.wikipedia.org/wiki/IP_address) defined in the list can connect to the database. Traffic from all other IP addresses is blocked. If you use [Redis Cloud Bring your Own Cloud]({{< relref "/operate/rc/subscriptions/bring-your-own-cloud" >}}) to host your Redis Cloud deployment, you can configure a subscription-wide allow list to restrict traffic to all databases associated with the subscription. The subscription CIDR allow list defines a range of IP addresses and [AWS security groups](https://docs.aws.amazon.com/managedservices/latest/userguide/about-security-groups.html) that control inbound and outbound traffic to the Redis Cloud [VPC](https://en.wikipedia.org/wiki/Virtual_private_cloud). When you add security groups to the allow list, you can also use the same security groups to manage access to your application. {{< note >}} The subscription-level allow list is available for Redis Cloud Bring your Own Cloud. If you don't have Redis Cloud Bring your Own Cloud, you can configure a [CIDR allow list]({{< relref "/operate/rc/security/cidr-whitelist" >}}) for each database. {{< /note >}} ## Allow IP address or security group To add IP addresses or [AWS security groups](https://docs.aws.amazon.com/managedservices/latest/userguide/about-security-groups.html) to a subscription's allow list: 1.
