If you have an Asus Router with Firmware you can now use its embedded DDNS client to update your No-IP hostname. By doing this you will no longer need to run our dynamic update client (DUC) on a local computer because the router will now be acting as the update client. To do this follow the steps below.

Step 1: Open up your favorite browser and go to the router’s default gateway address.

Step 2: Login to the router (common default values listed below).

  • Default Username: admin
  • Default Password: admin

Step 3: Click on “WAN” on the left hand side, then “DDNS” at the top.

Step 4: Enable DDNS functions in your Asus router and make sure you select “” as your server for DDNS.

You will need to use the following settings:

  • DDNS Server: You will select your DNS service provider
Username or email address: Enter in your No-IP account username or email address.
  • Password or DDNS Key: Enter your No-IP account password.
Hostname: Enter your No-IP account hostname or domain.


That’s it! As long as your Asus router is actively running, the device will check your IP address every few minutes. If it has changed we will send a notification to your account and update the desired host with the new IP address. This will prevent you from losing a connection simply because your IP address changed.

Note: No-IP Free hostnames are deleted after 30 days of inactivity. Inactivity is defined as when a host has not been updated or ‘touched’ from the web interface. No-IP Free hostnames must be updated once every 30 days. You can do this by logging into your No-IP account and clicking “Modify” next to your hostname then clicking “Update Hostname”. You can also follow the link in the email we send out 23 days before the host expires and fill out the captcha.

To eliminate the 30 day expiration notice you may want to upgrade to the No-IP Enhanced service.
