No git repository reachable from IPv6 networks
Trying to git clone /usr/src from a machine without IPv4 connectivity fails:
fatal: unable to connect to git.dragonflybsd.org:
git.dragonflybsd.org[0: 188.8.131.52]: errno=No route to host
Asia's IPv4 reserves are already exhausted and European ones should follow this year.
IPv6 reachable resources are needed to ensure DragonFly can be used by IPv6-only hosts.
