For WordPress Hosting and Managed WordPress (Learn more about your IONOS WordPress version)

By linking to a domain, your WordPress project becomes available at your own chosen Internet address. This article explains how to connect your domain.

Connecting WordPress with your Domain

  • Go to the Websites & Shops section of your IONOS account.
  • If necessary, click the Manage Website button in the corresponding tile of your project.
  • Click the Settings tab below the domain name.
  • In the Project Settings > Domain data group, click the Connect domain link. A listing of your registered domains opens.
  • Optional. Select Register Domain if you want to use a new domain.
  • Click on the row with the domain you want to use.

The selected domain will be connected to your WordPress project. Please note that this process will temporarily lock the ability to change other WordPress project settings.

SSL Encryption

Encryption of communication between a website and its users is an important factor for data protection on the Internet. For this reason, IONOS automatically sets up an SSL certificate for your domain.

Connect Project to External Domain

You can also connect your WordPress project to a domain that you have set up as an external domain in your IONOS account. The procedure is the same as for IONOS domains.


Please note that your external domain must use the IONOS name servers, otherwise a connection is not possible. If the connection cannot be established, we recommend checking the name server settings with your provider and adjusting them if necessary.
