Whether new names should be reserved, or their registration should be prohibited, is subject to ongoing assessment. These might be new generic domains, for example, if a new category of enterprise should emerge along the lines of AS (a limited-liability company); new geographical names, for example if new municipalities are created; new technical names in connection with the establishment of new services; and so on.

If names which may be relevant emerge, an assessment is undertaken in consultation with the LBDR Advisory Board of whether these names fulfil the requirements for inclusion in one of the categories in Appendix E1. LBDR may temporarily prohibit the names until a decision has been made. Notice of the decision that the names are to be added to Appendix E1 is given in the normal way, although for practical reasons the names will also be blocked during the notice period.

The addition of new names to the prohibited/reserved list will not have retroactive effect. This means that names that have already been registered will not be removed even if they are added to the list. If the name is deleted later, new registration of the name will however be blocked. Such names cannot be transferred to a new domain name holder either.
