WHOIS modifications for GDPR

The proposed solution aims at maintaining the original WHOIS purpose while protecting personal data in accordance with the GDPR and limiting abuses.


Terms and conditions are amended as of June 11th 2013

- Restriction regarding the registration of certain domain names which have been temporarily blocked has been abolished.

- Terms and conditions now incorporate appropriate provisions relating to the possibility to request a dispute entry (“Dispute”) for .lu domain names. Principles of such a Dispute are described hereafter.

Domain name blocking: introduction of Dispute entry as of June 11th 2013

The purpose for having registered a domain name Dispute by DNS-LU is to assist a claimant in finding a dispute agreement with a domain name holder in case a third party presents a credible case suggesting that it has a right to the domain or that its rights are being infringed by the domain.

The Dispute entry will only block the domain name which cannot be traded to anyone else but the claimant in case of the resolution of the underlying conflict. DNS-LU will not become involved in such disputes in any way, either in favour of the claimant or in favour of the domain holder.

The Dispute request has to be submitted to DNS-LU a form available at while joining supporting documentation proving the claimant’s rights (documents written or translated in French, German or English). Beside the claimant must have instigated formal measures vis-à-vis present domain holder.

The Dispute is valid for an initial period of one year and will expire without further notice. DNS-LU may, however, extend it for an additional period of six months, provided the claimant submits a formal request for this purpose.

In the event that the dispute is solved, the claimant must submit on his own initiative a formal trade request to any .lu registrar of his choice. This to ensure the proper transfer of ownership. The trade request will be checked and validated manually by DNS-LU subject to the reception of documents proving the resolution of the dispute in favor of the claimant.

In case of a domain name cancelation during the dispute period and no dispute resolution having taken place, the domain becomes available again for any interested party, without the claimant having a preferential registration right to the same domain name.

The new version of the Terms and conditions is available on since June 11th 2013

Technical and legal aspects of domain names

With the proliferation of domain names conflicts around these arise.

It is a relatively new kind of conflict with its own specificities and characteristics. So it is important for any party involved in such issues to have some basic knowledge of how the Internet works, the nature of possible disputes and how they might be arbitrated.

RESTENA Foundation has edited a guide destinated as a tool to provide some basic knowledge of eventual conflict resolution and the legal processes in this field.

Details of the registration process, which still need to be finalized, as well as the date of release, will all be published in due time on the DNS-LU website.

Luxembourg .lu domain names rank amongst the most secure in the world

The .lu domain is one of the world's securest top-level domains (TLD). That is the conclusion of an annual survey by US security software company McAfee. Luxembourg ranks on the 2nd position among the 27 EU countries, just behind Ireland. Luxembourg domain is 4th among worldwide country domains tested, where Japan (.jp) is the safest country domain globally, Ireland's .ie domain came second, followed by Croatia (.hr) and Luxembourg (.lu). McAfee checked out more than 5.750 .lu websites to arrive at the rating. Cameroon (cm) is the least secure domain worldwide. The risk of being infected by a computer virus when surfing is 69,7 percent when visiting a website from Cameroon (.cm). In Luxembourg, by contrast, it is only 0,3 percent. Of all the websites tested worldwide, 5.8 percent are rated as insecure.
"It is reassuring to see .lu in the upper part of the worldwide security level", said Antoine Barthel, managing director of RESTENA Foundation which operates the .lu registry DNS-LU. "McAfee's findings confirm that our continuous efforts and investments to make the .lu domain one of the most secure produce outstanding performances".
