returns both IPv6 and IPv4 address in that oerder.

The resolver returning IPv4 addresses for a pure IPv6 box would cause problems
all over the place, not only in bbox.

Configure resolver not to do that. Perhaps /etc/resolv.conf "options inet6".

If resolver can't be configured this way, try running DNS cache service
locally, configure it to only return IPv6, and point resolver to 127.0.0.1.
