I think you're right for IPv4. For IPv6, I'm tempted to treat it as a tabula rasa and explicitly not support NNNs. the rationale being that NNN support is to work around historical bad practice and such bad practice is not supported in the brave new world of IPv6. If that won't fly, then the IPv6 equivalent would be link-local (fe80::/64), site-local (fec0::/10) and ULAs (block fc00::/7), I think. > Nevertheless, I think we can safely proceed with this fix without being > sure that we have exactly the right definition of local address since > dnsmasq works no worse than libc in strict-order mode. > > ** Also affects: dnsmasq (Ubuntu) > Importance: Undecided > Status: New > > ** Also affects: resolvconf (Ubuntu) > Importance: Undecided > Status: New > -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/1003842 Title: dnsmasq sometimes fails to resolve private names in networks with non- equivalent nameservers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/1003842/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
