Hi,

It'd be nice to add IPv6 support for hosts files. I don't know if it's better to have all in one file or have separate v6 files but it can easily be done by adding :: telemetry-in.battle.net in addition to 0.0.0.0 telemetry-in.battle.net for instance. Would it be possible to do?

I would create a PR but I don't know how you generate and update the files.
