## Common questions

### Which Namecheap credential should I provide to Namecheap-DDNS?

Set NAMECHEAP_DDNS_TOKEN to the Dynamic DNS Password from Namecheap's Advanced DNS control panel. It is not your Namecheap login password.

### Does the domain need any special Namecheap DNS setup?

Dynamic DNS must be enabled, and the domain must be pointed to Namecheap BasicDNS, PremiumDNS, or FreeDNS.

### Can I update several subdomains or force a specific IP?

You can pass multiple subdomains with -s or NAMECHEAP_DDNS_SUBDOMAIN, and optionally set a specific IP with -i or NAMECHEAP_DDNS_IP. If no IP is provided, the updater uses the IP used to make the request.

### How can I schedule the updater on a Linux host?

Create a systemd service with the required environment variables and ExecStart path, then add a corresponding timer for scheduled runs.

### Can I use the same tool outside the container?

Yes, you can download pre-compiled binaries or install it with cargo install namecheap-ddns.
