IP Address Management That Ships the Policy That Enforces It
Amazon VPC IPAM with a top-level pool, a pool per region with netmask bounds and required tags, and optional sharing through AWS RAM. IPAM forces nothing on its own - a VPC can still take a hand-typed CIDR - so the module outputs the SCP AWS documents for requiring a pool. The provider defaults to the Advanced tier, billed per active IP, so the tier has no default here.

Documentation
aws-ipam
IP address management on Amazon VPC IP Address Manager. Works with Terraform and OpenTofu
(>= 1.6), aws provider >= 6.0, < 7.0.
IPAM does not make anyone use it. A VPC can still be created with a hand-typed CIDR. AWS's enforcement is an SCP denying VPC creation without an IPAM pool; enforcement_scp_json is that policy, and enforced_by_this_module says false until you attach it.
The Advanced tier is the provider's default and bills per active IP. tier has no default here.
A pool serves one region. A VPC takes a CIDR only from a pool whose locale is its Region, and a locale must be an operating region; both are checked at plan.
Allocation rules stop one team taking a /8: netmask bounds on every regional pool, and optional required tags.
Verification
Static validation runs tofu fmt, init, validate, tflint and checkov.
This module has not yet had a live test, so it is published as statically
validated with its live test pending and does not carry the live-tested mark.

Related modules
aws-vpc-lattice
auth_type defaults to NONE, so any client in any associated VPC can call any service with no identity and no policy - and associating one more VPC silently grants everything in it. Defaults to AWS_IAM and requires per-VPC security groups.
aws-vpc-peering
A VPC peering between two VPCs in one account and region, accepted in the same apply, with DNS resolution across it and routes written in every listed route table on both sides for every CIDR of the other. A default route through a peering is refused (CKV2_AWS_44). Peering is not transitive; past a handful of VPCs the transit gateway is the product.
aws-client-vpn
Remote-access VPN endpoint with certificate or SAML authentication, split tunnelling, per-group authorization rules and connection logging. There is no allow-all shortcut: an endpoint with no rule reaches nothing.
aws-cloud-map
Private DNS, public DNS or API-only namespaces and the services registered in them. Documents the health-check trap: a private namespace gets a custom check that something else must update, and one nobody updates reports healthy forever.
aws-cloud-wan
A global network whose segments, routing and attachment placement live in one policy document rather than per-region route tables. The policy VERSION is executed as a second step, so a change cannot report success while the network still runs the previous one.
aws-direct-connect
Gateway, connections, virtual interfaces and associations. A private circuit is a private path, not a private conversation: traffic crosses it in clear text unless MACsec is on, and should_encrypt quietly falls back to clear text.
