Bug Description

I just upgraded from 12.04 to 12.10 and suddenly I couldn't resolve the host. The ip and DNS was correct.
The nameserver in /etc/resolv.conf was 127.0.0.1. I changed it to the DNS directly and all went swell.

I had to install dnsmasq for it to work

I forgot to mention that I reverted the /etc/resolv.conf file back to original together with the dnsmasq for it to work.

/etc/resolv.conf containing 127.0.0.1 was correct, provided you have a local nameserver running that listens at IP address 127.0.0.1.

In Ubuntu 12.10, the dnsmasq process controlled by NetworkManager listens at 127.0.1.1, not at 127.0.0.1, so it wasn't NetworkManager that registered 127.0.0.1 with resolvconf.

My guess is that it was bind9 that did that, and that your problem was bug #933723.

For background information please read the following blog posting.

Not a NM problem; probably a dupe of #933723.
