Public bug reported:
ping to a mapped address
ping ::ffff:216.58.213.68
sends an ICMPv6 packet out onto the Internet with the mapped address in
the destination packet and the IPv6 address as the source. Mapped
addresses shouldn't appear on the public internet according to the RFC.
I would have expected this to use the IPv6 API to send an ICMP packet
over the v4 Internet on a dual stack machine in accordance with RFC4038.
