## Who points here
- **NetBird mesh peers:** nameserver group `home-lab-dns` (`hubris.network` → this server). *Note: the [NetBird managed DNS zone](124-authentik.md) still answers most app names directly, bypassing this — see the single-source-of-truth decision.*
- **Plain LAN clients:** router DHCP should hand out `192.168.8.2` (update the router — the old `.180`/dnsmasq is gone).
- **Homelab DHCP clients:** Technitium's own DHCP scope hands out `192.168.8.2` as the DNS server for `192.168.8.x` leases (see DHCP section below).
- **Plain LAN clients (`192.168.178.x`):** Fritz!Box DHCP still hands out Fritz!Box itself (`192.168.178.1`) as DNS — no split-horizon for non-mesh clients. Changing this requires a secondary DNS fallback, which Fritz!OS 8.x doesn't expose in a single DHCP field.
- **Secondary:** Mac Mini (planned, Phase 3) via AXFR zone transfer.
## DHCP
Technitium also runs a DHCP server for the homelab subnet (enabled 2026-06-02):
- **Scope:** `homelab` — `192.168.8.100 – 192.168.8.240`
- **Gateway:** `192.168.8.1` (Proxmox `vmbr0` alias)
- **DNS:** `192.168.8.2` (self)
- **Lease time:** 24 h
Replaces the DHCP that was previously served by the Slate AX router. Static-IP LXCs (below `.100`) are unaffected.

## Changelog
### 2026-06-02 — DHCP server enabled; replaces Slate AX DHCP
Enabled Technitium's built-in DHCP server for `192.168.8.0/24` (scope `homelab`, range `.100–.240`, gateway `192.168.8.1`, DNS self). Previously the Slate AX sub-router served DHCP for the homelab subnet. With the Slate AX retired and Proxmox now the subnet router, Technitium takes over DHCP. Configured via the Technitium API (`/api/dhcp/scopes/set`). DHCP LXCs kept their Slate AX leases until expiry, then renewed from Technitium.
### 2026-06-01 — created; replaced dnsmasq on 124
Stood up Technitium at `192.168.8.2`, imported the split-horizon zone (specific A + wildcard + MX/SPF/CAA), made it the primary nameserver in the NetBird `home-lab-dns` group. Verified all names resolve with dnsmasq/124 stopped; [LXC 124 retired](124-authentik.md).
