Many routers with DD-WRT firmware support custom Dynamic DNS. To configure it:
- Open your router's web interface and go to Setup > DDNS.
- Set DDNS Service to Custom.
- In the DYNDNS Server field, enter
dynamicdns.hostaday.com. - Use your domain as the Username and your DDNS Password as the password.
- Enter your host (e.g., @ or www) and save settings.
