2.0.0.2.ip6.arpa: NXDOMAIN e.f.f.3.ip6.arpa: NXDOMAIN That's probably 70-80% of all IP6 deployments reachable via the public ipv6 internet (granted, especially most 2002:: folks don't have reverse DNS set up yet, but plenty do...). It would be reasonable for glibc to at least make fallback to ip6.int an option... -- David Terrell | "Any sufficiently advanced technology Prime Minister, Nebcorp | is indistinguishable from a rigged demo."
