What is a server?

It is not unusual to see a 1U rackmount device called a "server"
in hosting data centres. These server things have 4 CPU chips
each with 4 cores, and 64G of RAM. Each of the 16 cores can run
at least 3 average virtual machines giving you 48 vms in the 
device, and it is common enough to see people running as many
as 7 or 8 VMs per core so you could easily have 112 VMs.

In addition to the 112 virtual servers, each needing a /128
for every one of their virtual network interfaces, it is common
to find people implementing virtual networks with virtual
routers and switches, including a virtual DMZ/firewall setup.

Clearly it is not unusual to find a so-called server device
that actually does require more than a /64 allocation in order
to remain aligned with IPv6 architecture and not start subnetting
/64 blocks.
