As from 11 June 2013, DNS-LU (Restena) will allow claimants to introduce a request to "freeze" a given .lu domain name, meaning that the domain name cannot be traded to someone else for an initial period of 1 year. This freezing period must allow the claimant and the holder of the domain name to resolve their dispute. Upon formal request, the freezing period can be extended for an additional period of 6 months.
