Also shame on Microsoft for no full IPv6 support in WSL2.

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)
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.
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:
If your ISP doesn't block ICMP, you can get IPv6 capabilities using tunnels like 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.
All of the links just go to Wikipedia and the traceroute is as shown (minus the initial hops of course)
