+### Interner DNS (CoreDNS) für VPN-Clients
+
+**Datei**: `deployment/ansible/playbooks/setup-infrastructure.yml` (Tag `dns`)
+
+**Verwendung:**
+```bash
+cd deployment/ansible
+ANSIBLE_VAULT_PASSWORD_FILE=secrets/.vault_pass \
+ansible-playbook -i inventory/production.yml playbooks/setup-infrastructure.yml --tags dns
+```
+
+**Konfiguration:**
+- DNS-Records definieren sich über `dns_records` (Default in `group_vars/production.yml` → `grafana.<app_domain>` → `10.8.0.1`)
+- Zusätzliche Einträge können per Override vor dem Playbook-Lauf gesetzt werden, z.B.:
+  ```bash
+  ansible-playbook ... --tags dns \
+    -e 'dns_records=[{"host":"grafana.michaelschiemer.de","address":"10.8.0.1"},{"host":"prometheus.michaelschiemer.de","address":"10.8.0.1"}]'
+  ```
+- Upstream-Resolver werden über `dns_forwarders` gesteuert (Standard: `1.1.1.1`, `8.8.8.8`)
+
+**Ergebnis:**
+- CoreDNS läuft auf dem Server via `network_mode: host` (UDP/TCP 53)
+- Alle VPN-Clients können `grafana.michaelschiemer.de` (und weitere Overrides) direkt auf `10.8.0.1` auflösen
+- Nicht hinterlegte Hostnamen werden dank `fallthrough` automatisch an die definierten Upstream-Resolver weitergereicht
+- Traefik-Middleware `grafana-vpn-only` akzeptiert ausschließlich Verbindungen aus dem WireGuard-Netz `10.8.0.0/24`
+- HTTP-Aufrufe zu Grafana laufen so automatisch durch den WireGuard-Tunnel
