I suppose we would find out how much broken software looked for "xn" rather than "xn--". I would be surprised if there were a lot of it. Have you ever run into anything that mishandles xn.examp1e.com ? Don't forget that RFC 5890 reserved all labels of the form XX--anything for any XX as R-LDH labels, even though currently only XN--anything is interpreted specially. _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
