Nope. Large scale DCs are IPv6 only underneath, exascalers like Google and Meta have stated that multiple times. I.e. https://www.youtube.com/watch?v=Q3ird3UDnOA also see various NANOG talks https://www.youtube.com/@TeamNANOG/videos

A great many home ISPs are also IPv6 only, and tunnel your IPv4 packets.

The underlay might be v6, but that doesn’t change the fact that people heavily use v4 for the actual workload traffic (i.e. the cloud computing part). EC2 VPCs still default to v4 only last time I checked.

Hyper scalers != cloud computing.
