Configuring Dynamic DNS (DDNS) allows you to access network resources using a domain name, even if your internet connection has a dynamic IP address that changes periodically. Here’s how to set it up:

 1. Sign Up for a Dynamic DNS Service:

• Choose a Dynamic DNS service provider. Popular options include No-IP, DynDNS, and DuckDNS.
• Create an account on the chosen Dynamic DNS service provider’s website.
• Follow the instructions provided by the service provider to set up a hostname (domain name) for your network.

2. Configure Your Router for Dynamic DNS:

• Access your router’s settings interface using a web browser.
• Navigate to the Dynamic DNS settings section. This is typically found under the “Internet,” “WAN,” or “Advanced” settings.
• Select the Dynamic DNS service provider you signed up with from the list of supported providers.
• Enter the hostname, username, and password provided by the Dynamic DNS service.
• Save or apply the changes.

 3. Test Dynamic DNS Configuration:

• After configuring Dynamic DNS on your router, your router will periodically update the Dynamic DNS service with your current IP address.
• You can test whether the Dynamic DNS is working correctly by entering your hostname (e.g., mydomain.ddns.net) into a web browser or using the ping command from the command prompt.

Step 4: Access Network Resources Using Domain Name

1. Once Dynamic DNS is set up and working, you can access network resources using the domain name you configured.
2. For example, if you set up port forwarding for a web server on your network, you can access it using the domain name instead of the IP address (e.g., http://mydomain.ddns.net).

 5. Troubleshooting and Maintenance:

• Periodically check that your Dynamic DNS hostname is still resolving to the correct IP address.
• Update your Dynamic DNS settings if your service provider’s credentials change or if you switch to a different provider.

Additional Tips:

• Some routers have built-in support for popular Dynamic DNS providers, making the configuration process easier.
• Make sure your router’s firewall allows outbound DNS traffic to the Dynamic DNS service provider’s servers.
• Consider enabling HTTPS for accessing network resources to ensure secure communication over the internet.

By following these steps, you can configure Dynamic DNS (DDNS) for accessing network resources with a domain name, making it easier to connect to your home or office network remotely, even if your internet connection has a dynamic IP address.
