ISC DHCP server with failover-peer (primary/secondary) deployed on
pfv-netinfra-01 (192.168.3.252) and pfv-netinfra-02 (192.168.3.253). Both
servers in "normal" state, load-balancing 333 active leases.
Migration details:
- Copied all 37 host reservations + subnet/pool config from pfv-netboot
- DHCP lease database copied from netboot for zero-disruption cutover
- DNS servers changed from 192.168.3.250 (netboot) to 252/253 (netinfra pair)
- NTP servers (252/253) added to DHCP options (netboot didn't hand out NTP)
- Netmask on both nodes fixed /24 -> /22 to match the network
- Webmin + DHCP module installed on both nodes (port 10000, SSL)
- pfv-netboot DHCP stopped + disabled
- Tested via sectestbed-sandbox (DHCP lease obtained from 252, verified DNS/NTP/gateway)
- Snapshot "pre-dhcp-migration" on sandbox as rollback point

Architecture
- Proxmox hosts: 7 standalone PVE installs managed via PDM
- DNS: Technitium (authoritative) + Pi-hole (recursive) on pfv-netinfra-01/02
- NTP: pfv-netinfra-01/02 (redundant, LAN IPs, stratum 2/3)
- Production: Cloudron VPS in Reston VA (this cluster is R&D only)
- Backups: Proxmox Backup Server (PBS)
