1. Understand How DDNS Work

Most ISPs assign dynamic IP addresses, meaning they change over time. A DDNS service updates your domain name whenever your IP address changes, ensuring consistent remote access.

2. Choose a DDNS Provider

Popular free and paid DDNS providers include:

• No-IP
• DynDNS
  DuckDNS
• Afraid.org
• Google Domains DDNS

Sign up for an account with your chosen provider.

3. Register a Hostname

After creating an account:

1. Log in to the DDNS provider’s website.
2. Add a new hostname (e.g., myhomeserver.ddns.net).
3. Select your update method (automatic or manual).
4. Assign the hostname to your public IP address (you can find this at https://whatismyipaddress.com/).

4. Configure Your Router (Preferred Method)

Many modern routers support built-in DDNS updating.

1. Access your router settings

   • Open a browser and enter your router’s IP (e.g., 192.168.1.1 or 192.168.0.1).
   • Log in with your admin credentials.

2. Find the DDNS settings

   • This is usually under WAN, Network, or Dynamic DNS settings.

3. Enter your DDNS provider details

   • Choose your provider from the list.
   • Enter your hostname, username, and password.
   • Save and apply settings.

The router will now automatically update your DDNS provider whenever your IP changes.
