This is fascinating. What are the implications of Indian users with only IPv6 stacks accessing IPv4 only sites? Does it look like potentially thousands of users accessing a site behind a single shared IPv4 address (i.e. CG-NAT)?
- SilverRed 6y agoFrom other comments previously, apparently your phone will only connect over ipv6 and then the ISP will manage forwarding your request over a shared ipv4 address. So yeah, it would look like many people on the same address. Thats pretty common globally. When ever I use my phone internet to connect to sites that use IP bans I find my self banned from most irc channels and other sites that I have never visited before.
- Aperocky 6y agoI wish more website can support ipv6 natively, but there's not a lot of pressure to do that in US as there are just so many ipv4 addresses lying around.
- kalleboo 6y agoAt least the wide adoption of CDNs like CloudFlare and CloudFront have had one positive effect - lots of sites have gotten IPv6 support "for free"
- perryizgr8 6y agoIt's never ipv6 only. There is an ipv4 address too. Not sure how that works, but ipv6-test.com shows both versions of addresses.
- Volundr 6y agoKind of. In practice your right, basically every ipv6-only ISP will run NAT64/DNS64 so you can access the ipv4 only web, but there's no technical reason they HAVE to, just a commercial one. And you have far less control of that ipv4 address than you would even a dynamic ipv4 assigned to your router.
- Dagger2 6y agoThat said, NAT64/DNS64 is v6-only from the perspective of clients on that ISP. The v4 internet will be mapped into a v6 /96, but from the client perspective it's just the same as any other v6 prefix.
