Domain Blocking prevents anyone to unlawfully transfer your domain to another registrar, or make changes to your domain that could harm you.
1. Blocking domain transfer
This is the highest possible level of protecting your domain against transfering it to another registrar without your permission. It is only possible to transfer a .CZ domain using the AUTH-ID, though there is a remaining risk of abuse often by misuse of the contact e-mail address in your domain record.
If you are interested in a complete blocking of of your .CZ domain transfer, please use the application of the central registry of .CZ domains, where this service is offered.
2. Blocking all changes to the domain
This service is blocking any possible changes to the domain, including transfer to another domain registrar. If you are interested in a complete blocking of all changes to your domain, please apply directly to the central registry. CZ domains, which offers this service.
Methods and possibilities of making changes:
Confirmation of changes is possible only with an officially authenticated signature or an e-mail signed by a qualified certificate. Any changes, including the transfer, can be made for Contact, Set of name servers and a Set of keys.
