[db-wg] Bug?

Hi! I got some troubles with web whois service at www.ripe.net. If my IP is 195.209.50.18 (IPv4) - I can do any queries. But if it is 2a01:d8:0:99:211:11ff:fe1f:bfc9 (IPv6) - I see this error message back to any of my queries (and to non-address queries too): %ERROR:203: address passing not allowed % % Sorry, you are not allowed to pass addresses on the query line. % Please contact us for such permission. For the moment, % continuing this will cause permanent denial of access. Mozilla Firefox tries IPv6 first if there is both addresses and connectivities... Is it a bug or a feature? -- WBR, Maxim V.
