Many ISPs are no longer handing out even 1 public ipv4 address per account, and instead opting for CGnat which further breaks and stratifies the internet.
Tmobile for example is 464xlat which is even worse than cgnat since it requires tampering with dns responses.
Given the situation many ISP are in, most serious companies offering services on the internet have supported ipv6 for a long time now in order to offer the most competitive service possible. And with cloudflare now serving up a large amount of traffic, a lot of all traffic is v6.
