Virtually every domain registrar uses its own configuration panel through which you can manage your registered domain. The panels can be very different from each other, but their functionality comes down to the same thing: allow you to edit so-called domain records. See how you can do it in a panel of one of the most popular Polish registrars.
After logging on to the panel, go to the My Domains section.
From the Available Actions drop-down menu, select the DNS Configuration. At the newly opened screen, find the row with the so-called "A record" for a domain:
Click Edit and in the next panel, change the IP address to the IP address of your OCI instance.
Finish by clicking Save button.
That's it: now you have to wait for an update of DNS configuration. The change should take up to 24 hours. After that typing the domain for your website will be opened straight from the Oktawave cloud.
