  0mq supports IPv6 for unicast and multicast excepting RFC6555
<http://tools.ietf.org/html/rfc6555>optimisations.  By default IPv6 is
disabled and can be enabled per socket with
ZMQ_IPV4ONLY.  There are multiple convenience enhancements for the
multicast side that do not yet have equivalents in the unicast side as
there is little demand: predominantly covering interface specification,
link-scope, and Teredo.

It may warrant a FAQ entry in the future, but it's pretty much a 1:1 for
IPv4 functionality for the majority of deployments.
