If you install the dnsmasq package then that package starts a standalone instance of the dnsmasq program and resolv.conf will contain a line `nameserver 127.0.0.1` which tells the resolver to consult that instance of the dnsmasq program, which will by default forward DNS queries to the nameservers which would otherwise have been directly consulted by the resolver.
The answer to the question "shouldn't those DNS servers should be included in /etc/resolv.conf regardless of the presence of dnsmasq?" is "no". Resolvconf doesn't list any nameserver addresses after any loopback address, unless TRUNCATE_NAMESERVER_LIST_AFTER_LOOPBACK_ADDRESS=no in /etc/default/resolvconf. When dnsmasq is installed does DNS function correctly? If so then there is no problem. ** Description changed: By default, when installing ubuntu-desktop (and when installing some other packages as well), apt will also install dnsmasq as a dependency. - When dnsmask is installed, and static IP addresses are used, resolv.conf + When dnsmasq is installed, and static IP addresses are used, resolv.conf creates a nearly empty /etc/resolv.conf file. The file only contains entries for localhost and the search domain. If static IP addresses are defined in /etc/network/interfaces, then shouldn't those DNS servers should be included in /etc/resolv.conf regardless of the presence of - dnsmask? + dnsmasq?
