+## Pi-hole
+
+Pi-hole runs **natively** on the Pi OS (not in Docker). It serves as the DNS server for the entire LAN — all clients including Gluetun on the homelab point to `192.168.2.112` for DNS.
+
+| Property | Value |
+|---|---|
+| Core | v6.3 |
+| Web Interface | v6.4 |
+| FTL | v6.4.1 |
+| Status | Blocking enabled, listening on port 53 (UDP+TCP, IPv4+IPv6) |
+
+> Updates available: Core → v6.4, Web → v6.4.1, FTL → v6.5. Run `sudo pihole -up` to update.
