128-bit submarine vs 32-bit destroyer reminded me of IPv6 vs IPv4.

Its fairly distinct. A destroyer is like owning a bunch of submarines, in a way. This is the one point where the model kind of breaks this layer, though.

Basically, it can't run out of address space because of the abundance of subs.

Thanks, sums it up pretty good.

And somehow makes it even more magical than when you read the docs.
