Whoever wrote this doesn't seem to quite understand how bit math works.

"IPv6 addresses are 128 bits long, compared to 32 bits long for IPv4. In other words, IPv6 addresses are 296 times more numerous than IPv4 addresses."

IPv6 addresses are actually 2^128/2^32 or 7.9e+28 times more numerous than IPv4, which would strengthen the argument that it's hard to be "wasteful" with them in the way described.

I get the impression that 296 is meant to be 2^96, which is exactly the same as your figure.
