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.

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
- stonekyx 4y agoIP 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.
- yyyk 4y agoYou're right. I didn't consider we don't control the other side's DNS server.
