Now looking at the NS RRset ns-sec.ripe.net returns for 2.0.0.2.ip6.arpa: == ns-apnic.6to4.nro.net. ns-arin.6to4.nro.net. ns-lacnic.6to4.nro.net. == ns-ripe.6to4.nro.net. soa @ns-apnic.6to4.nro.net. for 2.0.0.2.ip6.arpa. serial: 2004072901 dig @ns-arin.6to4.nro.net. for SOA of 2.0.0.2.ip6.arpa. failed soa @ns-lacnic.6to4.nro.net. for 2.0.0.2.ip6.arpa. serial: 2004072901 soa @ns-ripe.6to4.nro.net. for 2.0.0.2.ip6.arpa. serial: 2004072901 ==> ns-arin.6to4.nro.net == tinnie.arin.net, so we have the same IPv6 reachability problem again What a mess all over... why do ns.apnic.net and ns.icann.org return NXDOMAIN when queried for the NS RRset for 2.0.0.2.ip6.arpa, but ns-sec.ripe.net returning one? It looks like the whole 2.0.0.2.ip6.arpa is missing in the ip6.arpa zone, and ns-sec.ripe.net is only by chance carrying the 2.0.0.2.ip6.arpa zone, thus returning the NS RRset. I wonder where's the right place to report such global (multi-RIR/org) DNS problems to, if not v6ops. I see no "global IPv6 operations" list, can anyone enlighten me? Best regards, Daniel
