I agree with the reassignment - it is a network-manager issue. Here is the information requested, plus some more. Please ask for more if needed, and I you wish me to run some tests, tell me.
The system affected was originally created by Kubuntu 12:04 installer - to the best of my knowledge I have not deviated from what is default in that distribution with regards to network manager and dns configuration. The only vaguely relevant change I have made is to configure an IPSec based VPN. I included a piece of the syslog, mainly because it is a little different from the one in the original report: Sep 21 07:57:15 pcn-Latitude-E6520 NetworkManager[1271]: <info> (eth0): DHCPv4 state changed nbi -> preinit Sep 21 07:57:15 pcn-Latitude-E6520 dhclient: Listening on LPF/eth0/5c:26:0a:75:8f:b0 Sep 21 07:57:15 pcn-Latitude-E6520 dhclient: Sending on LPF/eth0/5c:26:0a:75:8f:b0 Sep 21 07:57:15 pcn-Latitude-E6520 dhclient: Sending on Socket/fallback Sep 21 07:57:15 pcn-Latitude-E6520 dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 3 Sep 21 07:57:15 pcn-Latitude-E6520 dhclient: DHCPREQUEST of 10.10.129.108 on eth0 to 255.255.255.255 port 67 Sep 21 07:57:15 pcn-Latitude-E6520 dhclient: DHCPOFFER of 10.10.129.108 from 10.10.129.2 Sep 21 07:57:15 pcn-Latitude-E6520 dhclient: DHCPACK of 10.10.129.108 from 10.10.129.2 Sep 21 07:57:15 pcn-Latitude-E6520 dhclient: bound to 10.10.129.108 -- renewal in 3421 seconds.

And now to your questions: The dnsmasq package is not installed, but the dnsmasq-base is, version 2.63-1ubuntu1. The only dnsmasq-releated configuration file present is /etc/dnsmasq.d /network-manager, with the content # Tell any system-wide dnsmasq instance to make sure to bind to interfaces # instead of listening on 0.0.0.0 # WARNING: changes to this file will get lost if network-manager is removed. bind-interfaces The /etc/resolv.conf file is not updated at all, so the content is probably not of any relevance - it is whatever it was the last time I edited it. Right now it is: # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN nameserver 192.168.253.251 nameserver 192.168.253.250 search intern.it-huset.dk - the two servers mentioned are nameservers on our house internal network. In normal operation (before I upgraded to 12:10 Beta 1) it says "nameserver 127.0.0.1". In /run/resolvconf/interface I find one file, NetworkManager with the content domain intern.it-huset.dk search intern.it-huset.dk nameserver 127.0.1.1 And finally, no, no other nameserver installed, specifically not bind.
