To host a domain on a server with Plesk Onyx, you first have to set up a hosting plan and then a subscription. A hosting plan defines which hosting resources and services will be provided. By setting up a subscription, you can subscribe to the hosting resources and services of the desired hosting plan. You can use add-ons to increase the number of resources and services provided at any time.
For each subscription, you can operate one or more websites with a single IPv4 or IPv6 address. To host multiple websites with different IP addresses, you have to set up additional subscriptions.
Please note: If you are not using automatic billing, you have to create a customer account and then sell a service plan subscription to the customer.
