This tutorial will show you how to set up Dynamic DNS (DDNS) on the ExpressVPN app for routers.

If your network uses dynamic IP addresses, it means the IP addresses assigned to devices change over time. A DDNS provides a fixed point of reference, called a static hostname. It is useful for hosting a server or website from your home, even if your IP address is continually changed by your internet service provider.

1. Get your DDNS hostname

Note: Dynu’s standard free service is sufficient for most users. The ExpressVPN router app also supports Duck DNS, No-IP, nsupdate.info, and DUIA.

Go to https://www.dynu.com and click Create Account.

Fill in the details, then click Submit. You will receive the account verification email from Dynu. If it is not in your inbox, check your spam folder.

Open the link in the verification email and log in to your account.

Select DDNS Services.

Click + Add to add a DDNS service.

If you do not have a hostname, create one and enter it in Option 1, then click + Add. Use this option if you are less familiar with domain names.

If you already have your own domain name, enter your domain name in Option 2, then click + Add.

You will now see your hostname at the top and your current public IP under IPv4 Address. Toggle the settings in the middle OFF, then click Save.

Your DDNS hostname is set up and ready to be used.

2. Configure Dynamic DNS on your router

Note: Before proceeding, make sure you have set up the ExpressVPN app on your router. You can read the setup instructions for the ExpressVPN app for routers.

Go to the ExpressVPN router dashboard. Sign in with your router admin password.

On the left sidebar, select Advanced Settings > Dynamic DNS.

From the dropdown menu, select the DDNS service you are using. (In this guide, we are selecting dynu.com.)

Enter your hostname account details. For Dynu, enter the following:

• Hostname: Enter the hostname you created earlier.
• Password: Enter your Dynu account password.

Select Save.

You will see a line that says “Update successful.”
