This is about Michael's (BCC'd) patch from 2013, lost in the space-time
vortex:

the almighty github seems to think this is still mergeable:

https://github.com/erlang/otp/compare/maint...msantos:epmd-IPv6-node-reg

As I can't see anything in the discussion that blocks this, can we have
it back please? IPv6 only is approaching (slightly faster than the heat
death of the universe) and I'd like erlang to be ready too.

I actually ran into this the last couple of days and the way I worked
around it was to create a local loopack 127.0.0.x address, and use this
trick from Bob Ippolito:

ERL_EPMD_ADDRESS=127.0.0.1 erl -kernel inet_dist_use_interface
"{127,0,0,1}" -name shell@REDACTED

It was on twitter but deserves to be easier to find in future than

I've been hoping epmd will be re-written in Erlang as legend has long
foretold :)

I updated the patch back in February and tried to follow some of the
recommendations in RFC 4038:

    https://github.com/msantos/otp/commit/e17240ad822c5d834ed6d756e64b54348424eda2

    https://github.com/msantos/otp/tree/epmd6-dual-stack-wip

The changes were tested on Windows 2012. There were some build failures
on Windows before but I don't know how similar these environments are.

I'll see if the patch still applies to the latest erlang and submit a
pull request.

Looks like there are a couple of other related-ish patches too:

https://github.com/erlang/otp/pull/602
https://github.com/erlang/otp/pull/706
