When a dual-stack lite host (dual stack capable, v6-only provisioned) wants
to send a v4 packet, it can simply put any v4 dummy address as source
address before shipping the packet through the v6 tunnel to the CGN. Even
0.0.0.1 will work as it will be replaced later by the CGN. The mapping will
be disambiguified by the tunnel ID (v6 src address).
