PIER, as contact person for a block of addresses, registered in the data bases of The InterNIC, I get many many "Network Number Usage Survey"s. The first ten-or-so I answered. However, I just received another dozen or so. When I would have been the official contact for all of these networks I surely would have answered all individual messages. However, all of these networks are in use in Europe, hence the data in the InterNIC data bases is not authoritative IMHO. For Europe, this information should be gathered from the RIPE data bases (whois.ripe.net). In the RIPE data base, in which SURFnet stores *all* of its information regarding networks, all correct contact persons can be found. Could you please query the RIPE data base as well, for networks in use in Europe?! Thanks. __ Erik-Jan.
