A default install of Docker Engine will have its IPv6 support disabled in `/etc/docker/daemon.json` in which case `ip6tables` will not have a `DOCKER-USER` or similar Docker-related chains. In this default setup having `update-firewall-source.py` generate an otherwise unused `DOCKER-USER` chain and adding rules to it clutters your rule set. Consider setting this to `true` if and when your Docker install uses IPv6.

A default install of Docker Engine will have its IPv6 support disabled in `/etc/docker/daemon.json`. You may still want your machine to handle incoming IPv6 traffic. If your machine truly doesn't use IPv6 feel free to leave this at `false`. Otherwise `update-firewall-source.py` generates unused rules that clutter your rule set.
 
   If this is `true` IPv6 addresses found or resolved in `addr` in a `[section]` will be discarded.
