Replying to no-body in particular. The discussion has been framed in terms of a service for particular TLDs or operators. I think that one argument has not been articulated. The DNSMON service has been used in the past to debunk a number of myths about the stability of the the DNS system as a whole. Those myths regularly reappear and may have (global) layer 9 implications. Therefor I think it is important that the data is provided by a monitoring service is ran by a technically competent and neutral party. In that context this task fits in the "the support of the stable operation of the Internet" and I would argue that it is a core activity of the NCC (given that that quote is from Article 3, objectives, of articles of association ;-) ) Since I can imagine that for ENUM there will be myths to be debunked I think that extending the service in that direction (tier 0 and 1 level zones) makes sense. hatless, --Olaf ----------------------------------------------------------- Olaf M.
