Disconnect your phone from Wi-Fi and visit https://ifconfig.co/ . If you're a Verizon customer, it's probably going to show you an IPv6 address. It's huge, right now, today.
Fair. I bet that'll change soon though. My prediction is that it'll be a mobile-first game, like the next Pokemon Go sort of thing, that'll be IPv6-only.
Plenty of mobile users use wifi at home/work. Telling them to disable their ipv4-only wifi just to play your game is going to be a non-starter, especially when the cost of ipv4 address adds negligible cost to infrastructure. Is your CTO really going to massively increase user friction ("turn of your wifi to play!") just so try to save a few cents (comparatively speaking) on infra?
this isn't true. I know because at some point XFinity started dropping ipv6 connections for me and I noticed because a number of sites (forget which) were broken
What do you mean by dropping ipv6 connections, like dropping ipv6 packets? That's only an issue if you're using v6. I disabled ipv6 on my router years ago and have never had a problem just using v4.
True, but irrelevant to my point. Whether a particular ISP supports doesn’t matter: it is being widely used by the rest of the world, to the point that it’s half of Google’s traffic.
Vodafone's network is reported to handle around 20% of the world's traffic. It's not a random ISP. It's network does not support IPv6. It is how a big chunk of all internet users experience the internet. Claiming it doesn't matter in a discussion over IPv6 adoption rate is ludicrous.
