Adding a domain you own to your DigitalOcean account lets you manage the domain's DNS records with the control panel and API. Domains you manage on DigitalOcean also integrate with DigitalOcean Load Balancers and Spaces to streamline automatic SSL certificate management.
If you no longer want to manage the DNS records for a domain on DigitalOcean, you can delete the domain. This removes the domain and its DNS records from the account.
To delete a domain, log in to the control panel and click Networking in the main menu to go to the Domains tab.
Open the More menu of the domain you want to delete, then click Delete. In the confirmation window, click Delete Domain to permanently delete the domain and its records from the account.
