Restore Process

To restore a domain as a RegistrarOC customer, you simply have to execute the RestoreDomain command. HEXONET directly forwards the restore request to the registry, which performs the restore in real-time. As soon as the restore is complete, the domain will get assigned to your account with the original domain data.

Please do not initiate a restore directly at the registry (e.g. using the registrar webinterface). All restore operations must be performed through our system.
