I would like to add new information and research that has been done in the Fedora project:
https://fedoraproject.org/wiki/Networking/NameResolution/ADDRCONFIG It links to related fedora bug reports which in turn link to upstream bug reports. It contains enough information about what is required to solve dualstack getaddrinfo() problems. We are working on this and invite anyone from the community to help us get rid of dualstack-related name resolution problems. Feel free to contact us. Contacts at the Fedora feature page: https://fedoraproject.org/wiki/Features/DualstackNetworking Or contact me directly: https://fedoraproject.org/wiki/User:Pavlix -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/417757 Title: [regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups Status in “eglibc” package in Ubuntu: Triaged Status in “network-manager” package in Ubuntu: Invalid Status in “eglibc” source package in Lucid: Triaged Status in “network-manager” source package in Lucid: Invalid Status in “eglibc” source package in Karmic: Fix Released Status in “network-manager” source package in Karmic: Invalid Status in “glibc” package in Fedora: Confirmed Bug description: In Karmic, DNS lookups take a very long time with some routers, because glibc's DNS resolver tries to do IPv6 (AAAA) lookups even if there are no (non-loopback) IPv6 interfaces configured. Routers which do not repond to this cause the lookup to take 20 seconds (until the IPv6 query times out). *** PLEASE DO NOT COMMENT ON THIS BUG unless you have something constructive to say. Everything that can be said has already been said, and if you comment, you are just adding noise. Please let those that actually know what they are doing concentrate on fixing this bug from now on. *** If disabling IPv6 or using good DNS servers like openDNS fixes the problem, you are not dealing with this bug.
