Ownerchange

All contact information with the exception of registrant Name, Firstname and Organisation can be updated through the ModifyDomain command.
In order to change the owner you have to request a trade with the TradeDomain command. This can be done through our web interface or through our API:

command = TradeDomain
domain = <DOMAIN>
ownercontact0 = <CONTACT>

Before a trade gets initiated at the registry, a confirmation is required: A fax form is required by the registry to process a trade. Once confirmed then the trade is initiated.

A Change of Registrar with the simultaneous change in the Registrant is not possible. Please be aware that domain name must be already managed by us. If the domain is currently managed by another registrar there are two possibilities:
   1.) first step: transfer the domain to us, second step: trade the domain with us.
   2.) first step: trade the domain with the current registrar, second step: transfer the domain to us.

command = ModifyDomain
domain  = (DOMAIN)

REQUIRED

ownercontact0 = (CONTACT)

X-NU-ACCEPT-REGISTRATION-TAC = 1 

Authorization Code

As of June 1, 2024, it will no longer be possible to set an authorization code manually. All auth codes are set by the registry. To retrieve the auth code, please use the ModidyDomain command with a random auth code. The registry will then respond with the current authorization code.

It will be valid for 14 days by requesting a new authorization code. You can generate a new authcode by removing the domain transfer lock.

RegistrarOC

Change of Registrant (Trade)

If you are RegistrarOC customer, you have to activate pending domain trades after receiving the fax form with the ActivateDomainTrade command. As RegistrarOC customer, you have the possibility to customize our fax form with your logo and your fax number.

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.
