IONOS: How to remove IONOS ads on empty domains?

If you register a domain with IONOS and do not use it directly, SEDO ads are displayed on the corresponding empty domain by default. Fortunately, this can be fixed.

Solution: In the IONOS customer backend, click on „Domains and SSL“ > at the bottom right on „Quick Access“, then select the item „Domain Parking“. There you can turn off the advertising.
