When investigating how the DNS setup of my os (Ubuntu 12.04) works, I came to some questions I could not really find on the web.
So what I observed was, that ubuntu uses Dnsmasq as a DNS resolver. When loooking into /etc/resolv.con, 127.0.1.1 is listed as nameserver.
So the question here is, if Dnsmasq is just used as a resolver and the resolver normally looks into /etc/resolv.conf to get the IP of the nameserver, how does this make sense?
It would only make sense if Dnsmasq was used as a local DNS server, meaning that the actual OS's resolver would send all DNS queries to the local Dnsmasq listening on port 53.
