12.04 running DNSMASQ by default
in 12.04 dnsmasq is now running by default due to being hardcoded into network manager.
Potentially bad idea (ever heard of DNS cache poisoning or MITM attacks ?)
12.04 Release Notes
5th Bullet Point.
Its built into Network manager now.
Running a local DNS caching server where your resolver is localhost or 127.0.01 may speed up DNS resolution but may also pose potential security risks.
You may do the following to disable it if you dont want it used, though it doesnt appear it to be caching by default (you can test with the dig command)
(the above is case sensitive so capital N)
sudo nano /etc/NetworkManager/NetworkManager.conf
and comment out the
line then do a
sudo restart network-manager
