+# DuckDNS
+
+DDNS updater running on box-stableapps (192.168.69.4). Updates two DuckDNS subdomains to point to the current public IP.
+
+## Subdomains
+
+| Subdomain | Full Domain |
+|-----------|-------------|
+| clintmasden | clintmasden.duckdns.org |
+| dotrepo | dotrepo.duckdns.org |
+
+## Credentials
+
+| What | Value |
+|------|-------|
+| Token | `4a5a3762-47eb-4836-89d8-60014bab4922` |
+| DuckDNS account | clintmasden@gmail.com |
+
+## Server Details
+
+| | |
+|---|---|
+| Host | 192.168.69.4 (box-stableapps) |
+| Container | duckdns |
+| Image | lscr.io/linuxserver/duckdns:latest |
+| Ports | None (outbound HTTP only) |
+| Config | `/home/clint/containers/duck.dns/config/` |
+| SSH | `ssh clint@192.168.69.4` (password: `this-bo%-180391`) |
+
+## How It Works
+
+The container runs a cron job that periodically calls the DuckDNS API to update the A records for both subdomains with the host's current public IP. No inbound ports needed.
+
+## Deployment
+
+```bash
+ssh clint@192.168.69.4
+cd /home/clint/containers/duck.dns
+sudo docker compose up -d
+```
+
+## Verify
+
+```bash
+# Check container logs
+docker logs duckdns
+
+# Check DNS resolution
+nslookup clintmasden.duckdns.org
+nslookup dotrepo.duckdns.org
+```
