About .lu

The .lu domain is Luxembourg's country code top-level domain (ccTLD), managed by RESTENA, a Luxembourg-based foundation that oversees the national research and education network. It is open to any individual or organization worldwide with no specific local presence requirements, though many local businesses and institutions prefer it for its strong tie to Luxembourg. Registration is handled through accredited registrars listed on the official registry site, dns.lu. The domain has been operating since 1995, making it one of the earlier European ccTLDs, and RESTENA continues to run the technical infrastructure from its offices in Esch-sur-Alzette.
