When and if there is a need for such activities, I'd propose to leave that to commercial entities. In that case it is extremely likely that the number of sites that close their nameservers for zone transfers will grow immensely. Probably. No, Wilfried: *extremely likely*. People are getting sick and tired of spamming and such and the idea of a commercial company "scanning" their nameservers (i.e. implying possible commercial abuse and even more spamming) would most certainly lead to massive blocking of zone transfers. But then it might be deemed useful to still allow access to the "RIPE Approved" sites doing the walk, and when there is a published document which describes the AUP for the data obtained? As soon as it would become clear that commercial companies would to the work, no AUP would help to overcome the fear for commercial abuse and (more) spamming. Piet
