Dynamic DNS With DDNS Keys


In order to configure Dynamic DNS, a DDNS Key must be created for your hostname.

This article covers:

  • How to create a DDNS Key
  • How to configure DDNS using your DDNS Key

 

Creating a DDNS Key

Creating a DDNS Key will be an option when creating your hostname. If you have already created a hostname, please review the following instructions.

  1. Navigate to the “No-IP Hostnames” page within your No-IP account.
  2. Find and click Create DDNS Key for your desired hostname.
  3. Click Generate DDNS Key. This creates the DDNS Key and opens the DDNS Key Setup modal.

The setup modal contains options to change the username to an email address (in case the update client requires it) and adding a friendly name.

This is your only opportunity to copy or save the DDNS Key password.

DDNS Key passwords cannot be recovered. If you lose your DDNS Key password, you must request another from the Modify DDNS Key modal.

Configuring Dynamic DNS

If the goal is to configure a remote connection to a device, you must next configure updates to the hostname (Dynamic DNS).

Dynamic DNS (DDNS) can be configured by utilizing the newly created DDNS Key’s assigned username and password.

Setting up Dynamic DNS requires access to a device that physically exists at the remote network and can be done one of two ways.

Our Dynamic Update Client (DUC) can be downloaded on Windows, Mac, or Linux.

Or

Using a device that supports No-IP. Routers, cameras, DVRs and most other devices that can be accessed remotely, support our Dynamic DNS service.

PC Setup
  1. Download and install our client on either Windows or Mac.
  2. Install and run the application.
  3. Enter your DDNS Key username and DDNS Key password.
  4. Select the checkbox adjacent to “all.ddnskey.com”.

If you plan to use the Linux client, you can follow our Linux installation instructions.

Router or Other Device Setup
  1. Log into your device. The manufacturer of your chosen device should have provided you with instructions on how to do so. If you lack instructions, check out our Configuring DDNS on a Router guide for some suggestions.
  2. Search for Dynamic DNS or DDNS settings. They are typically found under the “Advanced” options. DDNS settings differ depending on the device, but will typically contain the following fields:

DDNS Provider: No-IP
Username: Your DDNS Key Username / Email
Password: Your DDNS Key Password
Hostname/Domain: all.ddnskey.com
Server/Server Address: dynupdate.no-ip.com
Not every device will ask you for a server or server address. The service still works without issue if the device does not request it.

Fill in the fields with your own information and confirm your settings when finished.

all.ddnskey.com sends the IP address update to all hostnames associated to that DDNS Key. It is still possible to use your own hostname in the hostname field while using DDNS Keys.
+-Double Checking Your Configuration
The IP address on your selected hostname should match your public IP address. You can view your public IP address by checking our port check tool website while connected to the same network as the device being configured.

If the IPs do not match, double check the DDNS settings, check for any firmware updates, and ensure DDNS is Enabled.

Lastly, if your goal is establishing a remote connection to a device or a webpage, you will need to configure Port Forwarding.
