You are correct. IDNA2008 states only rules about single labels - this was a result of discussing the various ways in which labels can be put together into domain names. There is a very explicit discussion of "what can happen if you concatenate labels into domain names" in https://www.rfc-editor.org/rfc/rfc5893#section-5 - it ends with "Rather than trying to suggest rules that disallow all such undesirable situations, this document merely warns about the possibility, and leaves it to application developers to take whatever measures they deem appropriate to avoid problematic situations." TR46 was written by people who have far less DNS experience than the people who were involved in RFC 5891. The two groups did not agree at the time TR46 was first written, and while my impression is that TR46 has been revised to be more in line with IDNA2008 over time, I am not surprised that there are still cases where trying to interpret the two as saying exactly the same thing will fail. -- Reply to this email directly or view it on GitHub: https://github.com/whatwg/url/issues/543#issuecomment-1377486968 You are receiving this because you are subscribed to this thread.
