Creating and configuring a DDNS on No-IP

DDNS is a system used to maintain a hostname with an updated IP address. It is recommended for networks that do not have a fixed public IP address, so that the hostname will always update to the public IP address from which it is receiving queries.

The DDNS update configuration must be done using the account and Hostname. In this article, we will show you how to create an account and Hostname using No-IP.

If you have a MikroTik, you don't need to use No-IP. Here's how to use MikroTik's native function.

If you have purchased Lumiun DNS Pro or Education, we can provide you with a free DDNS hostname. Contact support to request it.

Creating an account on No-IP.

  1. Visit the No-IP website

  2. Click Sign Up.

  3. Create your account using real data.

  4. Confirm your account via the email you received.

  5. When you log in to your account, click on DDNS & Remote Acess → DDNS Records → Create Hostname.

  6. Fill in the requested information and select the Enable Dynamic DNS option. Click Create With DDNS Key.

  7. Enter a name for identification, and click Generate DDNS Key.

  8. Save the information on this screen: Username, Password (save this password, it will only appear once), and Hostname. Confirm by clicking Done.

Important: With the free version of No-IP, you can only create one DDNS. You must confirm your usage on a monthly basis via an email sent by No-IP itself.

That's it! The saved information is important to enter into the equipment that will keep your public IP updated.

To keep the Hostname up to date

This information must be entered into a device so that your public IP address remains up to date. The most common use is in routers, in the DDNS or Dynamic DNS option.

In addition to the router, you can use a client provided by No-IP, called DUC (Dynamic DNS Update Client). The client is installed on your computer (Windows, Linux, or MAC) and configured with your credentials and hostname. After configuring DUC, the hostname will be updated to the public IP address of the connection where the computer is connected.
