Update Client FAQs

I want to install an Update Client, how do I do it?

You need to install an update client on the network your host resides in for the service to function correctly. An update client notifies us when your IP address changes. Once your domain or hostname is configured in an update client, the IP address will be automatically updated in our servers whenever your Internet Service Provider changes it. Domains or hostnames should only be configured to update in a single update client that has been installed on the host network that you want the domain or hostname to point to.

We recommend you install the officially supported Dyn updater software on a host computer running on your network and have that update your hostname(s). This would require that you have a computer running on your network 24/7. You can download and find information about installing the Dyn Updater here:

You could also configure the built in update client in your router. Since routers are third party products we can't guarantee that they'll update your hostname correctly. For assistance setting up your router's update client please contact the manufacturer or your Internet service provider if they issued it to you.

What is an Update Client Key?

The Update Client Key is an extra security measure that can be enabled in your account by either a user clicking the "Generate Key" button in "Account Settings" in your portal, by clicking the banner on the top of the page, that appears when you have not generated the key yet, or by installing a 5.3 Dyn Update Client for your account.

Once this key is generated it will invalidate your password in all update clients you use for your account, and you will instead need to use the "Update Client Key" as your password. The purpose of this is so that you can have a different password used to log into your portal, than you will use for your update client to increase the security of your account.

Please keep in mind that not all routers are compatible with the "Update Client Key" as the key can sometimes be too long for those clients to allow. If this is the case, you are able to generate a shorter Update Client Key in your account settings.

I am having issues with the Update Client that is built into router, can you help?

Please contact your device manufacturer for specific assistance. We are unable to provide support for third party devices.

The general setup for your device is...
-Service: ( DNS/Dyn)
-Domain: (this isn’t always an option, but this would be the domain of your hostname)
-Host: (if the host you are updating is a subdomain, like they are in Dynamic DNS Pro, this will be the full hostname).
-Server Address:
-Username: Your username
-Password: Your password or updater client key. You can see if you have generated an updater client key by going to My Account > Account Settings at

Once those fields are completed, your device should start updating the IP automatically once it changes.

What is “Error 500" in the Dyn software Update Client?

This error is caused when the update client cannot obtain the WAN IP address. Please uninstall the update client, and delete the folder/directory that was created at install to ensure all files from the prior installation is deleted. You may need to use the Windows Disk Cleanup Utility or the equivalent on your OS to remove any other temporary files. You may then reinstall the client using the link below.

If you continue to experience issues or have already attempted this solution in its entirety it is recommended that you use the update client that came with your router. This is often a more stable and reliable update client.

Why is my host name IP address is a LAN IP (192.168.x.x or 10.0.x.x)?

This error typically occurs when your network is double NATed. This is generally caused by having 2 routers on the same network. In order to have your update client return the correct IP, please ensure your router is in bridge mode. If the error persists, we recommend using an update client that is built into your network edge router.

I am seeing an error in the Dyn software Update Client, what should I do?

Please send the update client log and details of the error to [email protected], so that we may research the issue further.

The log can be located by going to "View Details" and selecting "Legend". There will then be an option to export the log file. Please paste the logs into the body of your email.

I am experiencing general errors with the Dyn software Update Client (Windows), what should I do?

Please uninstall the update client and reinstall it as Administrator. The most recent version of the update client for your operating system may be found here:

Remnant files may remain in place after uninstalling the Dyn Update Client through the Windows ‘Programs and Features’ menu. We recommend using a file-scrubber / cleaner application that will uninstall and clear remnant files such as Cleaner. Alternatively, you may manually remove the files from the location of the installation path, specified during the initial installation. The default path is C:\ProgramData\Dyn\Updater\”.

You may then reinstall the update client, which should allow you to login successfully.

If the problem persists Windows has made a help guide to assist with uninstalling files that hold up a reinstallation.

I am experiencing general errors with the Dyn software Update Client (Mac OSX), what should I do?

This issue can usually be fixed by uninstalling all versions of the update client, and then reinstalling it. Please use the instructions below to uninstall the client, and if the problem persists let us know.

-Uninstall the updater (again) by dragging the app to the trash.

-Open up 'Finder' and press Command+Shift+G; type exactly: ~/.dynupdater

-Delete all files in the folder

-Reinstall the Dyn Updater.

This should clear all previous configs so that you can add your account again.

How can I fully uninstall the Update Client from my Mac?

Once you have uninstalled the application the normal way on a mac, you will need to perform the following Terminal command:

cd ~

rm -rf .dynupdater/

Be sure  to run it exactly as specified, if you forget to type .dynupdater/ on the second line it will delete the hard drive.
