I guess the site can only be reached over IPv6? It seems I only have IPv4 :(

Same, it begins. My ISP needs to get it's act together.

No A record, so I guess so. If your ISP doesn't block ICMP, you can get IPv6 capabilities using tunnels like https://tunnelbroker.net/ https://tunnelbroker.net/. Especially useful if you have a router you can configure this stuff on so all of your devices get IPv6 for free. Completely free of charge and with minimal latency if you live somewhere near a data centre.

  Netflix and friends won’t work over them. But with some clever routing, you can get it to work… I just got native ipv6 last winter and had to use tunnels like this for years.

I think it's reasonable to assume that this whole thing has been a marketing campaign to get people to finally have a reason to switch to IPv6. All kidding aside, IPv6 isn't even required for their website or this traceroute trick. He just set up an in-addr.arpa reverse DNS zone to reverse resolve particular IP addresses to specific values. If you had a block of 20 IPv4 addresses, I don't see anything stopping you from doing the exact same thing.

  >If you had a block of 20 IPv4 addresses, I don't see anything stopping you from doing the exact same thing. A block isn't necessary at all, even on IPv4. Traceroute can easily show internal address or just be lied to. Just recently we've seen a different example of this on HN: https://news.ycombinator.com/item?id=32566730 https://news.ycombinator.com/item?id=32566730

    IP addresses can be lied about, but reverse DNS still needs your ownership of those IP addresses if I understand it correctly. One would need the provider of those IP addresses to setup PTR records for them.

      You're right. I didn't consider we don't control the other side's DNS server.

That could be a feature if he didn't want to work at companies that don't have a IPv6 network :)

    apple.com is just a redirect to www.apple.com, which does have IPv6. Apple has been slowly but surely adding IPv6 to their public network services - App Store and OS downloads come over IPv6, and their NTP resolver just added IPv6 support. I guess the department that controls that apple.com -> www.apple.com redirect just hasn't bothered, which is interesting because such a simple, dumb redirect service is one of the easiest things to dual-stack (as in it probably doesn't store IPs or have to worry about blocking at all, it just responds with a 301)
