If IPv4 is like 640k, then, IPv6 is like having 47,223,664,828,696,452,136,959

unlikely we will see machines with much more than a terabyte of RAM
in the lifetime of IPv6.

I would be very careful with such predictions. How about 2 TB of RAM ?:

"...IBM can cram 1 TB of memory into a 4U chassis or 2 TB in an
eight-socket box in two 4U chassis..."

I don't know who will use it or how much they will need to pay for it or
even when they will be available,
but they are talking about it (in this case at the last CEBIT in March).

People are building some very big systems for example with lots and lots
of virtual machines.

On dell.com you can buy a PowerEdge R910 with 1TB RAM for around $80k.
