What are IBM Cloud domain-name systems services?

IBM Cloud® DNS Services offers public and private authoritative DNS services with fast response time, unparalleled redundancy and advanced security—managed through the IBM Cloud web interface or by API.

IBM Cloud domain-name system services translate requests for domain names into IP addresses, and all your domains can be managed through IBM’s user-friendly interface or by API.
