> Those phones are reaching half the internet via 64 gateways, no difference to reaching via 44 gateways.
And how would they have gotten first-hop connectivity without IPv6?
Comcast added IPv6 many years ago on their wired ISP side because they ran out of IPv4 for TR-069 management, and they had way fewer subscribers (at least at the time) than many mobile telcos.
And that half of the Internet is also some of the most bandwidth intensive stuff: Youtube, Netflix, Instagram. The CG-NAT hardware costs of streaming would be huge.
The network isn't just the open internet. There's also the part inside the network. You can view Comcast as a black box that magically gets packets from one side to the other, but Comcast engineers can't.
If you want to run a single massive scale network sure. One of the costs of scaling that the majority don’t see
No reason you can’t carry IPv4 over any protocol you want. Multi tennant vxlans can carry whatever you want over your base network. Maybe an IPv6 underlay makes sense there, doesn’t really matter
