For many years, applications for .lu domains could be made only via postal mail or fax. The fees for a .lu second level domain are €40 for the creation (or modification of a contact) and €40 yearly (including VAT).^[3] On 18 September 2006, the registry introduced a domain name registrar model.^[2] While the classic paper registration is possible, registering with a certified registrar is preferred by RESTENA.^[4]
