Namecheap DDNS
Dynamic DNS updater for dotrepo.com running on box-stableapps (192.168.69.4). Two containers keep the root (@) and wildcard (*) A records pointing to the current public IP.
DNS Records Updated
| Record | Domain | Container |
|---|---|---|
| @ (root) | dotrepo.com | ddns_dotrepo_at |
| * (wildcard) | *.dotrepo.com | ddns_dotrepo_wild |
Credentials
| What | Value |
|---|---|

| NC_PASS (DDNS password) | f1e2a12848f24995918b84760fd02b41 |

How It Works
Each container polls the Namecheap DDNS API to update its respective A record. The wildcard record (*) ensures all subdomains (audioevents.dotrepo.com, learnxiny.dotrepo.com, etc.) resolve to the public IP. Traefik then routes each subdomain to the correct container.
