If a name in /etc/hosts has more than one address associated with it, and at least one of those addresses is on the same subnet as the interface to which the query was sent, then return only the address(es) on that subnet. This allows for a server to have multiple addresses in /etc/hosts corresponding to each of its interfaces, and hosts will get the correct address based on which network they are attached to. Currently this facility is limited to IPv4. This option is available since (at least) `dnsmasq v2.60`. The result **without** this flag on two different machines (the first one is running `dnsmasq` locally): ``` pi@raspberrypi ~ $ dig +noall +answer raspberrypi raspberrypi. 300 IN A 192.168.2.10 raspberrypi. 300 IN A 127.0.1.1 me@desktop ~ $ dig +noall +answer raspberrypi raspberrypi. 300 IN A 127.0.1.1 raspberrypi. 300 IN A 192.168.2.10 ``` And **with** this flag: ``` pi@raspberrypi ~ $ dig +noall +answer raspberrypi raspberrypi. 300 IN A 127.0.1.1 me@desktop ~ $ dig +noall +answer raspberrypi raspberrypi. 300 IN A 192.168.2.10 ``` _This template was created based on the work of [`udemy-dl`](https://github.com/nishad/udemy-dl/blob/master/LICENSE)._

This to allow users to still add entries in the "/etc/hosts" file that will be read by dnsmasq to share with the clients.
Though the hosts file is not intended for that, allot of us (ab)use it like that anyway just for the ease.
Proper way is to configure dnsmask to load your own list of hosts and IP addresses to be loaded as DNS records.

I already implemented the "localise-queries" directive and without breaking loopback, everything looks dandy.
If you want to help out testing:

sudo rm /etc/dnsmasq.d/no-hosts-file.conf
echo 'localise-queries' | sudo tee /etc/dnsmasq.d/99-localise-queries.conf
sudo service dnsmasq restart
