Not in datacenters, where you'd typically have machines which run data
centers. With IPv4, most hosters tell you to configure a /24 netmask
on your interface. But this doesn't mean that you'll be able to use
more than the one IPv4 address the network has handed to you.
With IPv6, there are still technical reasons for limits, although
addresses aren't scarce: each address requires precious TCAM space,
and neighbor discovery does not work at scale.
