Correct, the only thing missing which is something I recently discovered is
called "Happy Eyeballs" - RFC6555.


I found this on a libcurl blog and as they haven't implemented it either:
it's a set of requirements for dual-stack environments to manage situations
when IPv6 connectivity fails and IPv4 is possible but with minimal delay
presented to the user.  I'm not aware of an actual algorithm that does
implement the requirements though.

By that description it may not to be too useful for ZeroMQ either.
