Precise Pangolin, or 12.04 is a long term support (LTS) release. One might think that particular care has been put into it. 11.10 (Oneiric Ocelot) has served me well during my first year in law school, but I thought that going on an LTS version will serve me better for the next two. Wrong.
Dnsmasq currently only listens on 127.0.0.1; that's done on purpose. If the only nameserver you have is 127.0.0.1, both IPv4 and IPv6 queries will go through it. It doesn't listen on an IPv6 address. We'll likely change the actual address to '127.0.1.1' as soon as this is possible with dnsmasq, there are changes coming up upstream that should support this.br /br /Letting dnsmasq listen on IPv6 is definitely something I wouldn't mind to see working; but it's unfortunately not as simple as adding '--listen-address=::1' to the parameters passed to dnsmasq by NetworkManager.
