To point your domain to IONOS, you will need to log in to your IONOS account and navigate to Domains & SSL section. Once there, click on Set up existing domain, enter the domain name, and select 1&1 IONOS Name server.
After you copied the values, you only need to change nameservers at your domain’s DNS Zone.
After you specify new NS records, propagation will start, which can take up to 24 hours to fully propagate.
That’s it! Now you know how to point your domain to IONOS 😊
