# Document history for IPAM The following table describes the releases for IPAM. | Feature | Description | Release Date | | --- | --- | --- | | [Bring your own IP to CloudFront using IPAM](tutorials-byoip-cloudfront.md) | Use IPAM to manage your BYOIP CIDRs for AWS global services, starting with CloudFront anycast services. | November 21, 2025 | | [Define public IPv4 allocation strategy with IPAM policies](define-public-ipv4-allocation-strategy-with-ipam-policies.md) | You can now use IPAM policies to define rules that map AWS services to specific IPAM pools, helping define public IPv4 allocation strategy. | November 19, 2025 | | [Integrate IPAM with Infoblox infrastructure](integrate-infoblox-ipam.md) | You can now integrate IPAM with Infoblox infrastructure, enabling you to manage AWS IP addresses through your existing Infoblox workflows while gaining cloud-native AWS capabilities. This integration is available for private scopes and requires IPAM Advanced Tier. | November 7, 2025 | | [Automate prefix list updates](automate-prefix-list-updates.md) | You can now use IPAM prefix list resolvers to automate prefix list updates based on IPAM pool CIDRs. | October 31, 2025 | | [Manage alarms from IPAM console](cloudwatch-ipam-manage-alarms.md) | You can now create and manage Amazon CloudWatch alarms directly from the IPAM console. IPAM-related alarms will appear as warning bars and visual indicators when in INSUFFICIENT\$1DATA or ALARM states. | August 21, 2025 | | [Enable cost distribution](ipam-enable-cost-distro.md) | When you enable cost distribution, you distribute the [charges for active IP addresses](pricing-ipam.md) to the accounts using the IP addresses rather than to the IPAM owner. This is useful for large organizations where the delegated IPAM admin manages the IP addresses centrally using IPAM and each account is responsible for their own usage, eliminating the need for manual billing calculations. | May 1, 2025 | | [Exclude organizational units from IPAM](exclude-ous.md) | If your IPAM is integrated with AWS Organizations, you can now exclude organizational units from IPAM. IPAM will not manage the IP addresses in accounts in organizational unit exclusions. | November 21, 2024 | | [AWS managed policy updates ](iam-ipam-managed-pol.md#iam-ipam-managed-pol-updates) - Update to an existing policy | Existing AWSIPAMServiceRolePolicy updated. | November 21, 2024 | | [Allocate sequential Elastic IP addresses from an IPAM pool](tutorials-eip-pool.md) | IPAM now enables you to provision Amazon-owned public IPv4 blocks to IPAM pools and allocate sequential Elastic IP addresses from those pools to AWS resources. Sequential Elastic IP addresses enable you to simplify your networking and security allowlisting needs. | August 28, 2024 | | [Private IPv6 GUA and ULAs](enable-prov-ipv6-gua.md) | You can now provision private IPv6 GUA and ULA ranges to an IPAM pool in a private scope. Private IPv6 addresses are only available in IPAM.
