Our Dynamic DNS Update Client continually checks for IP address changes in the background and automatically updates the DNS at No-IP whenever it changes.

Secure Key Based Updates
Our secure DUC does not resend your No-IP credentials each time it sends an IP address update, instead it sends a unique key for username and password for your specific Dynamic Update Client.

Client Tracking
This feature allows you to see a list of each location where you have a DUC installed. You can also set each update Client ID to a custom name for example, home, work, client name, etc to help keep track of each.

Host Creation
You are able to easily add hostnames directly from the Dynamic Update Client.

Runs on Login
Once you log in, we will check to see if your IP address has changed. If it has, we will update your hostnames with the new IP address

Automatic Updates
We will now be able to push updates out automatically to keep your client up-to-date with the latest version.

Runs on OS X 10.10 Yosemite & up
Running an earlier version of OSX? Download the DUC v3.1.5 (for OSX 10.4 - 10.6) or Download the DUC v3.2.1 (for OSX 10.7-10.9).


The installation will complete and the application will ask for your account information. After your No-IP username and password have been authenticated you will be shown a list of your hostnames. Select the hostnames that you would like updated to the IP address of your computer.
