      In Landingi, you can publish your landing page to your own subdomain. A free Let's Encrypt SSL certificate will be automatically added for every correctly installed subdomain.


      This guide will show you how to set up a domain registered with 1&1 IONOS.

      Access the DNS management zone in 1&1 IONOS

      1. Log in to your 1&1 IONOS account.

      2. Go to the My Products section and select Domains & SSL.

      3. To redirect a subdomain to Landingi, you have to first create it. Click on Add subdomain under the Quick Links menu.

      4. Type in a subdomain name. Click on Save.

      5. Click the gear icon under Actions next to the subdomain you want to redirect and select DNS.

      Set up the DNS records

      Now you need to configure the DNS records, select the type of your subdomain.

      Before you start, read about www subdomain redirection.

      1. Add two A records: one for your root domain and one for the www subdomain. If you already have these records, edit their values.

      2. Copy and paste the following values:

      Type A

      Host Name:
      @
      Target:
      157.53.227.1
      Type A

      Host Name:
      www
      Target:
      157.53.227.1

      3. Save the changes.

      1. Add an A record for the subdomain you want to add to Landingi. If you already have such a record, edit it.

      2. Copy and paste the following values:

      Type A

      Host Name:
      your subdomain name, e.g., promo for promo.domain.com
      Target:
      157.53.227.1

      3. Save the changes.

      Finish the configuration in Landingi

      When you're ready, go back to Landingi and click on Confirm/Finish.

      Once you've added the subdomain to your account, our system will verify whether the DNS redirections have been done correctly. During this time, an hourglass icon will be visible next to the domain with the information that the domain is being verified. Usually, the domain will be active a few hours after adding it, but the total waiting time depends on the number of domains in our system waiting in the queue to install the certificate. We will email you when the domain is installed correctly.

      A green globe icon indicates an active domain. You can assign it to your landing page.

      In some cases, you have to wait between 1 and 24 hours for the records to propagate.
