Questions and answers

  • What is the purpose of SIDN Recovery?

    The purpose of SIDN Recovery is to provide a secure and reliable system for recovering domain names that have been suspended or deleted. SIDN (Stichting Internet Domeinregistratie Nederland) is the registry for .nl domain names in the Netherlands. When a domain name is suspended or deleted, SIDN Recovery allows the rightful owner of the domain to reclaim it by following a specific recovery process. This ensures that domain names are not permanently lost and can be returned to their legitimate owners.

  • How does the SIDN Recovery process work?

    The SIDN (Stichting Internet Domeinregistratie Nederland) recovery process is designed to help users recover control over their domain names in case of accidental deletion, expiration, or unauthorized transfer. Here is a general overview of the SIDN recovery process:

    1. Identify the issue: The domain owner realizes that their domain name is no longer under their control, either due to accidental deletion, expiration, or unauthorized transfer.
    2. Contact the registrar: The domain owner should first contact their registrar, the company through which they registered the domain name. The registrar will investigate the issue and try to resolve it if possible. If the issue cannot be resolved by the registrar, they will initiate the SIDN recovery process.
    3. Registrar's request to SIDN: The registrar submits a recovery request to SIDN, providing all the necessary information about the domain name, the issue, and the attempts made to resolve it.
    4. SIDN's investigation: SIDN reviews the recovery request and verifies the provided information. They may contact the domain owner and registrar for further details or evidence. SIDN ensures that the recovery request is legitimate and that the domain owner has the right to regain control over the domain.
    5. Recovery decision: Based on the investigation, SIDN makes a decision regarding the recovery of the domain name. If the recovery request is approved, SIDN takes necessary actions to return control of the domain name to the rightful owner.
    6. Domain recovery: Once the recovery request is approved, the domain owner can regain control over their domain name. This may involve updating the domain's registration details, renewing the domain, or transferring it back to the owner's registrar account.

    It is important to note that the recovery process may vary slightly depending on the specific circumstances and policies of the registrar and SIDN.

  • What are the eligibility criteria for participating in SIDN Recovery?

    SIDN Recovery is a service provided by SIDN, the registry for .nl domain names in the Netherlands, to help recover expired or deleted domain names. The eligibility criteria for participating in SIDN Recovery are as follows:

    1. The domain name must have been registered under the .nl top-level domain (TLD).
    2. The domain name must have expired or been deleted within the last 40 days.
    3. The domain name must not have been transferred to another party or re-registered by someone else.
    4. The domain name must not be involved in any legal disputes or conflicts.
    5. The domain name must not be subject to any pending or completed legal proceedings.
    6. The registrant of the domain name must have a legitimate interest in recovering it.
    7. The registrant must be able to provide sufficient evidence to support their claim of legitimate interest.

    It is important to note that meeting the eligibility criteria does not guarantee successful recovery of the domain name. SIDN will evaluate each case individually and make a decision based on the provided evidence and their own policies and procedures.
