What makes the response incorrect? I was under the impression that DNS implementations were under no "practical" obligation to return consistent queries to differing requester IP addresses (hence stuff like split-horizon DNS and EDNS: https://developers.google.com/speed/public-dns/docs/ecs )
Sorry, to clarify: when archive.is receives a DNS lookup from Cloudflare’s resolvers, they reply with an IP in the 127.0.0.0/8 range, so the origin client is unable to connect (since those IPs aren’t routable over the internet).
Thanks for the clarification on here + and the other posts, that makes perfect sense.
It is deliberately invalid.
