== IPv4 in IPv6 ==
The weirdest and most interesting one: suppose you have equipment that is not IPv6 compatible, yet you want to connect them through a v6-only link between the two endpoints

Machine A:
<pre>
ip -6 tunnel add v4tun mode ipip6 local 2a00:ffde:4567:edde::4987 remote 2001:473:fece:cafe::5179
ip addr add 192.168.99.1/24 dev v4tun
ip link set dev v4tun up
</pre>

Machine B:
<pre>
ip -6 tunnel add v4tun mode ipip6 remote 2a00:ffde:4567:edde::4987 local 2001:473:fece:cafe::5179
ip addr add 192.168.99.2/24 dev v4tun
ip link set dev v4tun up
</pre>
