📝 WalkthroughWalkthroughChangesThe IP helpers now return Typed IP generation and propagation
Estimated code review effort: 3 (Moderate) | ~30 minutes Merge Risk: 🔵 Low · up to The refactor now returns structured IP address objects, while one fixture still passes those values into fields documented as strings; runtime formatting currently preserves behavior, but the contract should be aligned. Additional stale test metadata and import-policy inconsistencies remain, so the PR is mergeable with explicit owner follow-up. 🚥 Pre-merge checks | ✅ 6✅ Passed checks (6 passed)

## Test Execution Plan
**Run smoke tests: False.** The only affected smoke-marked file is `tests/storage/cdi_upload/test_upload_virtctl.py`, but its smoke test does not request `primary_udn_for_upload`. That fixture is the only changed-helper path in its local `conftest.py`.
**Run gating tests: True.** Verified paths:
- `tests/network/nmstate/test_connectivity_after_nmstate_changes.py::TestConnectivityAfterNmstateChanged::test_connectivity_after_nncp_change` → `nmstate_linux_bridge_attached_vma` / `nmstate_linux_bridge_attached_vmb` → `random_ipv4_address`.
- `tests/network/user_defined_network/test_user_defined_network.py::TestPrimaryUdn::test_connectivity_is_preserved_during_client_live_migration` → `client` / `server` → `vma_udn` / `vmb_udn` → `namespaced_layer2_user_defined_network` → `random_ipv4_address`.
- `tests/network/localnet/test_default_bridge.py::test_connectivity_over_migration_between_localnet_vms` → `localnet_running_vms` → `vm_localnet_1` / `vm_localnet_2` → `ipv4_localnet_address_pool` and `ipv6_localnet_address_pool` → `random_ipv4_address` / `random_ipv6_address`.
- `tests/network/kubemacpool/test_kubemacpool.py::TestKMPConnectivity::test_automatic_mac_from_pool_pod_network`, `::test_automatic_mac_from_pool`, and `::test_mac_preserved_after_shutdown` → `running_vm_a` / `running_vm_b` → `vm_network_config` → `random_ipv4_address`.
**Affected tests to run**
- `tests/network/nmstate/test_connectivity_after_nmstate_changes.py::TestConnectivityAfterNmstateChanged::test_connectivity_after_nncp_change` (gating)
- `tests/network/user_defined_network/test_user_defined_network.py::TestPrimaryUdn::test_connectivity_is_preserved_during_client_live_migration` (gating)
- `tests/network/localnet/test_default_bridge.py::test_connectivity_over_migration_between_localnet_vms` (gating)
- `tests/network/kubemacpool/test_kubemacpool.py::TestKMPConnectivity::test_automatic_mac_from_pool_pod_network` (gating)
- `tests/network/kubemacpool/test_kubemacpool.py::TestKMPConnectivity::test_automatic_mac_from_pool` (gating)
- `tests/network/kubemacpool/test_kubemacpool.py::TestKMPConnectivity::test_mac_preserved_after_shutdown` (gating)
- `tests/storage/cdi_upload/test_upload_virtctl.py::test_virtctl_image_upload_dv_in_pudn_namespace`
- `tests/network/bgp/evpn/test_evpn_connectivity.py`
- `tests/network/l2_bridge/test_l2_linux_bridge.py`
- `tests/network/l2_bridge/test_bridge_nic_hot_plug.py`
- `tests/network/l2_bridge/nad_ref_change/test_nad_ref_change.py`
**Real tests (cluster required)**
Error path: verify validated prefix bounds.
`pytest tests/network/flat_overlay/test_flat_overlay.py --collect-only`
Expected: collection succeeds with `subnet_length=32`; invalid prefix values raise `ValueError` before a resource is created.
Happy path: verify interface serialization and bare-IP consumers.
`pytest tests/network/nmstate/test_connectivity_after_nmstate_changes.py::TestConnectivityAfterNmstateChanged::test_connectivity_after_nncp_change tests/network/user_defined_network/test_user_defined_network.py::TestPrimaryUdn::test_connectivity_is_preserved_during_client_live_migration tests/network/localnet/test_default_bridge.py::test_connectivity_over_migration_between_localnet_vms`
Expected: VM network data accepts serialized `IPv4Interface`/`IPv6Interface` values, and connectivity succeeds.

Review generated by pi
Assisted-by: PI (claude-opus-4-6-1m)
The random_ipv4_address and random_ipv6_address helpers previously returned plain strings, requiring callers to manually append prefix lengths and making the type opaque. Returning IPv4Interface/IPv6Interface gives callers access to the structured IP data (.ip for the bare address, .network for the subnet) without string parsing, and lets subnet_length be explicit and validated. Callers that need a non-standard mask, may call `subnet_length=` with the requested cidr. YAML serialization is handled at the dataclass boundary so EthernetDevice callers pass interface objects directl with str() conversion.

## Test Execution Plan
**Run smoke tests: True.** `tests/storage/cdi_upload/test_upload_virtctl.py::test_virtctl_image_upload_dv` is smoke-marked. Its parent hierarchy includes `tests/conftest.py`, which calls the changed `random_cidr_addresses_by_family` helper in shared VM fixtures.
**Run gating tests: True.** Verified paths:
- `tests/network/nmstate/test_connectivity_after_nmstate_changes.py::TestConnectivityAfterNmstateChanged::test_connectivity_after_nncp_change` → `nmstate_linux_bridge_attached_vma` and `nmstate_linux_bridge_attached_vmb` → `random_ipv4_address`.
- `tests/network/user_defined_network/test_user_defined_network.py::TestPrimaryUdn::test_connectivity_is_preserved_during_client_live_migration` → `client` and `server` → `vma_udn` and `vmb_udn` → `namespaced_layer2_user_defined_network` → `random_ipv4_address`.
- `tests/network/localnet/test_default_bridge.py::test_connectivity_over_migration_between_localnet_vms` → `localnet_active_connections` → `localnet_running_vms` → `vm_localnet_1` and `vm_localnet_2` → `ipv4_localnet_address_pool` and `ipv6_localnet_address_pool` → `random_ipv4_address` and `random_ipv6_address`.
- `tests/network/kubemacpool/test_kubemacpool.py::TestKMPConnectivity::test_automatic_mac_from_pool_pod_network`, `::test_automatic_mac_from_pool`, and `::test_mac_preserved_after_shutdown` → `running_vm_a` and `running_vm_b` → `vm_network_config` → `random_ipv4_address`.

Error path: validate the `/32` prefix path.
`pytest tests/network/flat_overlay/test_flat_overlay.py --collect-only`
Expected: collection succeeds with `subnet_length=32`. Invalid IPv4 prefixes outside `24..32` and IPv6 prefixes outside `64..128` must raise `ValueError` before resource creation.
Happy path: validate interface serialization and connectivity.
`pytest tests/network/nmstate/test_connectivity_after_nmstate_changes.py::TestConnectivityAfterNmstateChanged::test_connectivity_after_nncp_change tests/network/user_defined_network/test_user_defined_network.py::TestPrimaryUdn::test_connectivity_is_preserved_during_client_live_migration tests/network/localnet/test_default_bridge.py::test_connectivity_over_migration_between_localnet_vms`
Expected: cloud-init receives CIDR strings, and the VMs retain connectivity.
SR-IOV cluster with hardware:
`pytest tests/network/sriov/memory_hotplug/test_sriov_memory_hotplug.py`
Expected: `IPv4Interface` and `IPv6Interface` values serialize into the SR-IOV cloud-init network data, and connectivity succeeds after memory hot-plug.
Cluster without SR-IOV hardware:
`pytest tests/network/sriov/memory_hotplug/test_sriov_memory_hotplug.py --collect-only`
Expected: collection succeeds without attempting to create SR-IOV resources.

What this PR does / why we need it:
The
random_ipv4_addressandrandom_ipv6_addresshelpers previously returned plain strings, requiring callers to manually append prefix lengths and making the type opaque.Returning IPv4Interface/IPv6Interface gives callers access to the structured IP data (.ip for the bare address, .network for the subnet) without string parsing, and lets subnet_length be explicit and validated.
Callers that need a non-standard mask, may call
subnet_length=with the requested cidr.Which issue(s) this PR fixes: -
