   no-resolv
   # use cloudflare as default nameservers, prefer 1^4
   server=1.0.0.1
   server=1.1.1.1
   strict-order
   # serve all .company queries using a specific nameserver
   server=/company/10.0.0.1
   # explicitly define host-ip mappings
   address=/myhost.company/10.0.0.2

   $ docker run \
   	--name dnsmasq \
   	-d \
