Thank you for your concern. As others have pointed out, PowerDNS 
supports both v4 and v6 quite well.

Indeed we do not use sockaddr_storage - most sockaddr structures inside 
PowerDNS are stored inside what we call a ‘ComboAddress’ which is a 
union of _in and _in6, providing benefits similar to _storage, even to 
the point of being compatible with it.

That said, at a quick glance I think the HTTP API in the Recursor might 
be using _in wrong. If you feel like digging deeper, please have a look 
to see if you agree, and if there are any other places in which we 
actually do it wrong.

In any case please file a ticket so we can correct the Recursor 
situation (the issue is in Socket.accept()).

Kind regards,
