Slow dns resolving

[flomsk]

Hello @aacebedo
Thank you for great tool, it's make easier to control containers)
But I have some (bug?)
On the host system I paste to first line in resolv.conf
nameserver ip-addr-of-docker0-interface
After that I can resolv container by dns name.
But inside the containers something terrible happens

root@app:/# dig www.google.com

4001msec!!!
What I'm doing wrong ?
I started dnsdock with
docker run -d -v /var/run/docker.sock:/var/run/docker.sock --name dnsdock -p 172.51.42.1:53:53/udp aacebedo/dnsdock:latest-amd64

Hi

How many containers are running when you text this feature ?
On which platform are you running dnsdock?
