resolv.conf containing 127.0.0.1

I have just installed Ubuntu 12.04 on a dual-stack network (with managed IPv6 configuration). I would like to verify if the DNS resolver options received from DHCP and DHCPv6 servers are correct.

Normally, I would check /etc/resolv.conf, but on Ubuntu it contains only 127.0.0.1. It would be a bit far-fetched to assume that Ubuntu is running a recursive DNS resolver by default, so I think the actual resolver settings are somewhere else.

Where would I check this?

you can use nm-tool, to check which DNS-server you are using right know.

just run nm-tool without any parameters. Here is the interesting part from the output:

[...]

IPv4 Settings:

    Address:         192.168.5.126

    Prefix:          24 (255.255.255.0)

    Gateway:         192.168.5.1



    DNS:             192.168.5.1
