IPv6 for Luddites

Andrew (aka mcnalu) recently triggered Beni by saying that he turns off
IPv6
in order to get devices working on his home network. In this show Beni educates Andrew the
Luddite
and explains why moving from IPv4 to IPv6 is a good idea. They also explore how IPv6 can be used in a world where ISPs and devices do not all support it and what tools, tips and tricks are available during this rather long transitional phase to the newish (like 30 years old, a blink of an eye in IT) protocol.
