It's surprising that the number of non-traversable hosts is only 4-8%. Aren't most cellular (3G/4G) users behind symmetric NAT, or is this considering only PC users?
- callesgg 12y agoAll the cellar stuff I have used in the last 5 years have given me public open ip addresses. So i don't think that is the case.
- dmm 12y agoAs of at least summer 2013 Sprint no longer offers public ips with new phones. It's all carrier-grade NAT. T-Mobile is the same but they provide ipv6, though with just a single ipv6 address which doesn't make any sense. I'm not sure about the other carriers.
- RustyRussell 12y agoTheir product doesn't do mobile, that's why. My 3G in Australia is definitely NATed (and the source address the other end sees seems to change with each cell!).
- api 12y agoNAT isn't why it doesn't do mobile. It doesn't do mobile yet because there are issues around battery life that have to be solved. Mobile will take the addition of a sleep mode and the use of mobile push notification busses.
- api 12y agoI didn't mention carrier-grade NAT, but it's almost always full-cone and traversable. ZeroTier works behind tethering behind carrier-grade cellular NAT.
