# NOTE: Since Docker 1.10 (February 4, 2016), it has been possible to configure the
#   Docker daemon using a JSON config file.  On Linux, this file is normally located at
#   /etc/docker/daemon.json.  You should use this JSON config method if you are running
#   a version of Docker that is at least 1.10!
#   Here is an example configuration that sets the docker0 bridge IP to 192.168.254.1/24:
#   {
#     "bip": "192.168.254.1/24"
#   }

Configure systemd-resolved to use a specific DNS nameserver for a given domain

Use case

Given

• I use a VPN to connect to my work network
• I'm on a Linux computer that uses systemd-resolved
• I have a work domain called example.com
• example.com is hosted by both public and private DNS nameservers
