Network Infrastructure Assumptions for Packer Builds

This ADR is retained as a historical record of early Packer networking assumptions.

The current source of truth for network design and build-time connectivity is:

• ADR-0101 – VLAN Allocation Strategy
• ADR-0102 – Proxmox as Intra-Site Core Router
• Network Architecture
• ADR-0016 – Packer + Cloud-Init VM Templates

In summary, Packer builds still assume:

• A management VLAN with DHCP/DNS and outbound package access.
• Proxmox bridges already connected to that network.
• Packer does not spin up ad-hoc DHCP or mutate host networking; it consumes the existing fabric.

Operational detail and current commands live in:

• Packer multi-OS workspace
• Runbook: Proxmox Packer Template Build
