Having taught a bunch of IPv6 courses opening with a photo of Gaurab
and his "96 more bits, no magic" tshirt and then having dealt with the
confusion once we get in to the nitty gritty details, I am inclined to
agree with you here.
The intention of these sorts of statements is to remove the "I will
have to learn IP all over again" fear (and the associated "it's too
hard" etc.), but you are right, this has been causing people to get a
bit surprised when stuff does not work the same as IPv4.
I suppose it is fair to say that in the core of the network, it is
essentially 96 more bits, and no magic. The access network is where
this becomes a bit of a confusing statement.
Anyway, comments taken on board, I'll have a think about how to do
