See this answer, this make possible to run a container and solve it by hostname at host machine, it would be helpful for development

docker run --rm --hostname dns.mageddo --name dns-proxy-server -p 5380:5380 \
  -v /opt/dns-proxy-server/conf:/app/conf \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v /etc/resolv.conf:/etc/resolv.conf \
  defreitas/dns-proxy-server

Running a test container

docker run --hostname nginx.dev.intranet nginx

Testing it
