If you want to compare masses, IPv4 = 7 liters of water.
IPv6 = EARTH, including all rocks, trees, oceans, lakes, puddles,

Put another way, if subnets (IPv4 /24s, IPv6 /64s) were
Almond M&Ms, IPv4 would cover approximately 70 yards
of a regulation American Football field in a single layer of

IPv6 would fill the great lakes. All of the great lakes.
To the rim.

In terms of host addresses per subnet, IPv4 gives you
a large bag of M&Ms. IPv6 gives you the great lakes
full of M&Ms. All of the great lakes. To the rim.

as adverse health results are likely.
