Very true. Verizon has been 6 only for ages, but they use NAT64 so most non-nerds never noticed.
I believe that at the time of the rollout they were the largest IP6 network on the planet. They may still be.
It works because smartphone users don't have the same needs as home and business users. There aren't a ton of smartphone users demanding reachable IPv4 addresses in the first place, and the ones who might want them are probably smart enough to figure out how to use IPv6 instead.
- jandrese 9y agoI can't imagine there is much demand for people running internet servers off of their phone over the cell network.
- stevenAthompson 9y agoYou might be surprised. For instance, almost every emergency vehicle has a 4G modem of some sort in it now. Also, there are tons of vending machines and assorted manufacturing or mining equipment that use similar devices. Often it's nice to be able to reach out to those devices and check the location, status, or whatever instead of waiting for the device to check in with you. For those purposes though IPv6 is fine... as long as you know what you're doing with IPv6.
- dx034 9y agoDoesn't that decrease security? NAT plays a big role in anonymising users and providing some basic security. If every device has their own ipv6 address, scanning devices for vulnerabilities will be much easier. Having secure devices is obviously the better solution but will never happen. That 10 year old vending machine won't get an update anytime soon and hiding it from the outer world could be the best way to prevent it being part of a botnet.
- gsich 9y agoWhy? Just because you have a global address? This does not mean that all inbound connections are open. Also scanning IPv6 is not that easy as it is in v4.
