Just for reference ZONEMD switched two fields between draft-wessels-dns-zone-digest-05.txt and RFC 8976. "Digest Type | Reserved” -> "Scheme | Hash Algorithm”. This resulted in BIND rejecting zones with ZONEMD records using SHA-512 digests (digest field has the wrong length for Digest Type 1). Renaming fields is fine. Reordering/repurposing non reserved isn’t as it breaks stuff. Now we are making BIND compatible with RFC 8976 but we should never have been put in this position. > --Paul Hoffman_______________________________________________ > DNSOP mailing list > DNSOP@ietf.org > https://www.ietf.org/mailman/listinfo/dnsop -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: ma...@isc.org _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
