Unfortunately, glib quips that conflate multiplication with
exponentiation help perpetuate people's gross underestimation of the
vastness of the address space we're talking about here.

Let's restate that quote as:

first it was 2^8
then 2^(8*4) = 4.2 * 10^9
then 2^(8*4*4) = 3.8 * 10^38
and he assumes 2^(8*4*4*4) = 1.3 * 10^154

(the last equation suggests enough addresses to give 10^74 addresses
to each atom in the visible universe.  dealing with a routing table to
do this or pinging each address in non-universe-epochal-time is out of
scope for this discussion).
