General principles

Entity responsible for .lu domain name management

The RESTENA Foundation is responsible for the .lu top-level domain, a responsibility which was given to it by the Internet Assigned Numbers Authority (IANA) in March 1992. In this capacity, it deals with technical and administrative performance. This function is known as Registry.

Registering a domain name

You have chosen a domain name, checked that it is available and would now like to register it. Domain names are allocated on a first-come, first-served basis. In other words, the first entity to register the name it wants prevents any other interested parties from doing so.

The registry has a network of accredited agents who act as companies legally independent from DNS-LU working on behalf of their own clients. These registrars are therefore obliged to comply, within the context of their transactions, with technical standards and administrative procedures laid down and monitored by DNS-LU. In addition, DNS-LU also performs the role of registrar and you can therefore contact DNS-LU directly to register your domain name.

For further details, please see below.

Underlying principles of .lu domain name registration

The Domain Name Charter contains all the principles (registration policy) applied by the registry for domain name registration. These principles apply to all registrations regardless of the registrar chosen.

Preamble to the Domain Name Charter

Domain Name Charter

It may be that someone else has rights over an available domain name you want to register. To avoid future conflict, it is important to make sure that, before registering your domain name, you are not infringing the rights of third parties. In the Registrants FAQ a whole paragraph is dedicated to the registry’s policy on disputes over .lu domain names. See also “Disputes associated with .lu domain names” below.

A domain name cannot be registered

here is a possibility that you want to register a .lu domain name that turns out to be already allocated to another registrant.

Choose another name and check it using the Whois service to see if the name you want is still available. If you think you have rights over a particular name, you must contact the current holder to come to an amicable agreement or initiate proceedings. The registry does not get involved in disputes between domain name holders and third parties.

The domain name is not authorised for registration under the .lu top-level domain name. There may be several reasons for this:

- the requested domain name does not comply with the Domain Name Charter;

- the syntax of the domain name is incorrect.

Only letters (a-z), numbers (0-9) and hyphens (-) are allowed. A domain name may not start or end with a hyphen (-). Names with less than three (3) or more than sixty-three (63) characters are not accepted; accented characters are accepted to a certain extent since February 1st 2010; refer to next paragraph;

- the domain name you want is supposedly an Internationalised domain name (IDN) but includes at least one character not accepted under .lu.

Please check that the non-ASCII character used is one of those accepted under .lu. IDNs are domain names that have, besides the 26 ASCII letters in the alphabet, the 10 figures and the hyphen, accented characters or other special characters.

Nameserver registration

Nameservers indicate the machines on which your domain name is registered. If this registration is missing, your website cannot be found. A registration without a nameserver can still be useful if you want to register a domain name but you do not intend to prepare and host the site until a later date.

In order to register a domain name with nameservers, the corresponding name and address, obtainable from your internet service provider, are required.

Domain name management

Domain name registration is treated like a subscription. It is renewable each year and can be terminated by relinquishment or by transfer to another holder or can even be revoked by the registrar.

As a domain name holder, you are responsible for maintaining the information held on record. It is important that you keep all registration information up to date and complete. If, for example, renewal is not paid for due to a problem with the billing address or because the manager cannot be contacted, the domain name will be cancelled. The website, email and other services that use the domain name will become inactive.

Invoicing and payment

Payment can be made against an invoice or by credit card, depending on the management option chosen. Failure to make all or part of a payment may result in the loss of the domain name.

Registration data updates

If you move premises or change your email address, remember to update the registration data for your domain name. Please be aware that a change in the head of the domain name holder is, in principle, only possible through a “name trade” procedure. See below for information.

Transfer or cancellation of domain names

By making a cancellation request, you can relinquish the registered domain name. It is released for re-registration after a transitional period of thirty days.

You can also trade your domain names with another company or individual. To do this, the new holder should enter into a new registration contract and pay for a new subscription period.

Similarly, the registrar can be changed and management of your domain names transferred to another accredited agent if its services suit you better.

GDPR - Additional Information

In accordance with legal enactments, a limited amount of information can be consulted for a given domain name through the Whois service. The registry has taken steps to prevent the systematic collection of data and the transmission of unwanted email marketing messages (spam). Access to personal data is regulated by its own Terms and Conditions in accordance with GDPR as of May 2018. For more information regarding the new whois following the implementaion of the GDPR, go to web page GDPR.

Disputes associated with .lu domain names

The Domain Name Charter, including the Preamble give details of the registry’s policy on disputes relating to .lu domain names. This policy is based on the fact that domain name holders acknowledge that the registry never arbitrates in disputes arising from registration and use of a domain name. It is the responsibility of anyone who considers a domain name to have been registered unfairly or illegally, or who feels they have been wronged by such a registration, to take action against the domain name holder and to either obtain a court ruling or to settle the conflict through an extrajudicial agreement. DNS-LU’s role is limited to implementing any court or extrajudicial decision made against it, without DNS-LU being obliged to check, on its own initiative, the definitive nature of such a decision or of the potential existence of contradictory decisions returned in other jurisdictions, whether they relate to the same dispute or not.
These rules apply regardless of the registration and management option chosen, whether the classic method has been used or the registration has been done online with DNS-LU or an accredited registrar.

DNS-LU may, however, assist any claimant who feels that his rights have been infringed by a domain by filing a formal Dispute entry.  To find out who the holder of the domain is and thus who is to be contacted in case of an infringement of rights or in case of technical problems caused by the domain., our Whois service may be used as described in the underlying Whois Use Policy in agreement with GDPR.

In case of management through DNS-LU as registrar, their own Terms and Conditions are furthermore applicable.

DNS-LU has edited a guide for those who would like to get a more indepth knowledge related to legal and technical issues in the field of domain names and conflict resolution particularly. The guide is available in french language only on homepage.
