My provider traced the problem and today they said [.] der [.] eingesetzte BIND [hat] in der Kombination aus den Flags des anfragenden Client [.] und den autoritativen Nameservern [.] Probleme [.] the used bind has problems in the combination of the flags the client uses, and the authoritative servers on the other side. With a lot of "shall" and "possibly". Anyhow, they pointed me to a PowerDNS server now. (Now i get a lot of errors with the dnsbl.sorbs.net i use, but whatever ;) In the meantime i had placed the freebsd domain in /etc/hosts, most other failing lookups refer to spam domains that i do not care about. Ciao. P.S.: the possibility to make dnsmasq authoritative for IPv6 when it yet only served IPv4 via an entry in a --dhcp-host file would be fantastic. (Or, maybe even better yet, even if it did _not_ yet serve any DHCP related, but a query for a name that has an IP assigned there, or a name which only has a MAC, i.e., pre-reserve that IP, maybe? Thanks for dnsmasq.) --steffen | |Der Kragenbaer, The moon bear, |der holt sich munter he cheerfully and one by one |einen nach dem anderen runter wa.ks himself off |(By Robert Gernhardt) _______________________________________________ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk https://lists.thekelleys.org.uk/cgi-bin/mailman/listinfo/dnsmasq-discuss
