Since you have "nameserver 127.0.0.1" in "/etc/resolv.conf", I'd guess
that you have dnsmasq running and that it forwards your queries to
208.67.222.222 and 208.67.220.220 when you specify them in
"/etc/network/interfaces".
If you are running dnsmasq, "ps ax o cmd | grep dnsmasq" should give
you the full command that launched it as well as the file that has the
"external" dns servers (that's what I used on a new Ubuntu 12.04
desktop install on which resolvconf and dnsmasq are installed by
default; the server's been spared dnsmasq...).
