The domain owner (registrant) is the legal or natural person who has registered the domain in their name. This entity holds the rights to the domain and has the authority to transfer, renew, or terminate its registration. In the case of CZ domains, the owner is recorded in the CZ.NIC registry, and their information may be publicly accessible unless they are an individual who has opted for identity protection services.

Who is the administrative contact of a domain?
The administrative contact is a person or entity responsible for managing the domain but does not necessarily own it. This contact is primarily used for communication with the registrar regarding changes or technical issues. The administrative contact can be:

  • The domain owner themselves,
  • A designated manager, such as an IT specialist or a hosting provider,
  • Another authorized person with permission to perform specific actions related to the domain.

Key differences between a domain owner and an administrative contact

  1. Legal status – The domain owner holds legal rights over the domain, while the administrative contact is only a representative for management.
  2. Decision-making power – Only the domain owner can make critical changes, such as transferring the domain to another holder.
  3. Responsibility – In case of disputes or legal matters, the domain owner is the primary contact, not the administrative contact.

Who can be a domain owner and who can be an administrative contact?

  • The domain owner can be an individual, a company, or an organization.
  • The administrative contact can be anyone designated by the owner—most commonly technical support, a hosting provider, or a company employee.

Why is it important to have properly configured contacts for a CZ domain?

  • Security and control – Incorrectly set contacts can lead to issues in domain management.
  • Efficient communication – A properly chosen administrative contact ensures effective resolution of potential problems.
  • Protection of ownership rights – Unclear ownership details may lead to complications when recovering or transferring the domain.

How to check and update contact details for a CZ domain?
Contact details can be verified through whois.nic.cz. If a change is needed, it must be made via the registrar where the domain is registered.


Properly setting up the domain owner and administrative contact is crucial for the security, management, and smooth operation of your website. While the owner holds all rights, the administrative contact mainly acts as a manager and a liaison with the registrar. Paying close attention to these details can help prevent issues with your CZ domain.
