Conversation
📝 WalkthroughWalkthroughThe network API and render pipeline now support IPv6 GUA allocation and automatic IPv4/IPv6 resource-planning pools. Status output, examples, validation targets, render tests, and observed-resource fixtures reflect the new allocation flow. ChangesIPAM network allocation
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The PR adds cross-account IPAM planning pools and direct subnet allocation, but the recommended example cannot currently reconcile with the stated provider, and the build targets may report success after failed render or validation jobs. A teardown-safety concern also remains, so the change is not merge-ready until these issues are fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

In `@apis/networks/definition.yaml`:
- Around line 103-117: Update the ipv6Gua schema validation so poolId is
required whenever enabled is true, preventing configurations that render an
empty ipv6IpamPoolId; preserve the existing optional behavior when enabled is
false.
In `@examples/networks/with-ipam.yaml`:
- Around line 28-33: Update the comment immediately above subnetLayout to remove
the incorrect cidrmath description and clearly state that subnet CIDRs are
allocated from the VPC resource-planning pools, instructing users to create
those required pools.
In `@README.md`:
- Around line 510-519: Update the README network status example to show ipv6Ula
and ipv6Gua as mutually exclusive allocation modes, matching the precedence
logic in the network renderer; split the example into separate ULA and GUA
alternatives or explicitly mark the fields as alternatives, and do not present
both fields together.

unchanged and matching the step 2 VPC’s CIDR.

In `@functions/render/50-subnets.yaml.gotmpl`:
- Around line 83-124: Update the IPv4 and IPv6 planning-pool Usage conditions in
both public and private subnet blocks to depend on stable observed
planning-pool, CIDR, and subnet IDs rather than transient pool or subnet
readiness flags. Keep each Usage rendered while those identifiers remain
available, preserving the deletion barrier across readiness changes.
In `@Makefile`:
- Around line 126-128: Update the validate:% recipe to enable Bash pipefail with
set -o pipefail; immediately before the up composition render pipeline, ensuring
render failures propagate even when crossplane resource validate succeeds.
In `@README.md`:
- Around line 473-478: Update the resourcePlanning settings table to document
resourcePlanning.ipv4.externalName, resourcePlanning.ipv6.externalName, and
resourcePlanning.ipv6.publicIpSource, including their types and behavior,
especially pool import support and the byoip selection.

Summary

/16→ planning pool/16→ subnet/20or/24, and Regional GUA/52→ VPC/56→ planning pool/56→ subnet/64.Reconciliation behavior
Dependent resources gate on observed IDs, not transient readiness, so a readiness blip cannot un-render live subnets. Usage resources remain readiness-gated.
The RAM share is managed by the existing Foundation/RAMShare APIs and is not implemented inside this Network XR.

crossplane-contrib/provider-aws-ec2:v2.7.0cannot create a planning pool sourced from a VPC in another account because its vendored Upbound Terraform AWS fork still performs an invalidDescribeVpcscall from the IPAM administrator account. HashiCorp fixed this in terraform-provider-aws#46483, released in v6.56.0.The live bootstrap used a one-time AWS CLI create followed by declarative Crossplane adoption through
externalName. The pools are fully managed after adoption; no OpenTofu or provider fork is involved. The provider packaging gap remains tracked intasks/provider-aws-ipam-resource-planning-cross-account.Related: terraform-provider-aws#34615
