It was announced in November 2005 that the initial registration of domains would be free until the beginning of 2006, though with some limits on the number any individual was allowed to register. This was remarkably popular, with some 17,000 registrations coming in on the first day of the promotion.
Domain names are registered directly at second level. Some of Belgian's main academic institutions, such as the Vrije Universiteit Brussel and the Université Libre de Bruxelles, use third-level names under ac.be, but others have abandoned its use (Katholieke Universiteit Leuven, Universiteit Gent and Université Catholique de Louvain).
Any .be registration has to be ordered via a registered agent.
