The alternative to Domain Delegation is now to use Primary DNS along with the ability to have your HTTP load balancer manage your DNS records. For more information, see Create Primary Zone and look for the new option, Allow HTTP Load Balancer Managed Records in Step 5: Optionally enable DNSSEC and load balancer management.
Existing Delegated Domains will need to be migrated to one of the new Distributed Cloud solutions, but they will continue to function properly during this migration period.
Coming soon - F5 is working on a structured migration path to help customers with this change.
