> Dial keys. Not IPs.
  > It's a simple idea really, and it's the right abstraction for the future of the internet. IP addresses can break, without warning, and it's outside of your device's control. Keys, however, are created & controlled by you. They stay the same as your device moves, and are yours to throw away, or not. IP addresses can be private and inaccessible behind firewalls, but with iroh your device can be securely addressable no matter where it is.

The biggest difference that I can see is that keys are not making any claims about ownership, there's no global registry and it's p2p, which is a big upside

No idea why this is downvoted, it's exactly the pitch for DNS. Others and I are asking the same question. There's no value proposition here.
