What is Dynamic DNS (DDNS)?

Dynamic DNS (DDNS) is a service that automatically updates the DNS records for a domain name when the associated IP address changes. Unlike traditional DNS, which requires manual updates, DDNS ensures that your services remain accessible to the internet even if the IP address assigned by your ISP changes. This is particularly useful for web hosting, remote access, and video surveillance services hosted on dynamic IP addresses.

How do I set up DDNS on my router?

To set up DDNS on your router, follow these steps: Access your router's web management interface by entering the default IP address (e.g., 192.168.1.1 or 192.168.0.1 ) in a web browser. Navigate to the DDNS settings section, usually found under Setup or Network. Select Custom as the DDNS service provider. Enter the DDNS server details: DDNS Server: ddns.oray.com User Name: Your AweShell account username Password: Your AweShell account password Host Name: The domain name you want to use for the DDNS service URL: /ph/update? Click Save to apply the changes. Verify the configuration by checking the DDNS Status field, which should display Update successful.

What should I do if my domain name does not resolve to the correct IP address?

If your domain name does not resolve to the correct IP address, it is likely due to DNS cache. You can resolve this issue by: Restarting your computer to clear the local DNS cache. Using the command ipconfig /flushdns in the command prompt to clear the DNS cache without restarting your computer. Modifying your network configuration to use a DNS server with a shorter synchronization time, such as Google's public DNS server ( 8.8.8.8 ).

Can I use multiple domains with the same DDNS service?

Yes, you can use multiple domains with the same DDNS service. If you have multiple domains pointing to the same service, you can add them to the DDNS configuration. This allows you to manage all your domains from a single DDNS service.

How can I ensure the security of my DDNS setup?

To ensure the security of your DDNS setup, follow these best practices: Use strong and unique passwords for your DDNS client and router. Enable any additional security features provided by your router and DDNS service. Regularly monitor the status of your DDNS service to detect and address any issues early.
