I'm not sure if this is the same bug I'm experiencing, but if I try to access a domain without IPv6 address, I get this on tshark:
0.000000 192.168.2.103 -> 192.168.2.254 DNS 74 Standard query AAAA one.ubuntu.com 0.074500 192.168.2.254 -> 192.168.2.103 DNS 135 Standard query response 0.074682 192.168.2.103 -> 192.168.2.254 DNS 95 Standard query AAAA one.ubuntu.com.internal.eudemo.info 0.075854 192.168.2.254 -> 192.168.2.103 DNS 95 Standard query response, No such name 0.075991 192.168.2.103 -> 192.168.2.254 DNS 74 Standard query A one.ubuntu.com 0.147486 192.168.2.254 -> 192.168.2.103 DNS 106 Standard query response A 91.189.89.219 A 91.189.89.218 As you can see, between the AAAA and the A resolution there's a wrong query with my local domain added: this is the one which takes a few seconds to fail (not in this case because I have setup my dnsmasq with local=/internal.eudemo.info/ to get a fast response) I have tested it with both Firefox and Chrome and both do the same, so I assume is a system problem. Is this the same problem or I need to open a separate bug report (or something is wrong with my setup)? -- 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.
