There is no excuse for 8-bit failures under the DNS specifications. More importantly, there is no evidence of 8-bit failures in real DNS servers. > As this working group has discovered multiple times now, > case-insensitivity is not precisely defined for many non-ASCII > scripts. RFC 1034 says ``case-insensitive manner, assuming an ASCII character set.'' The obvious interpretation, and the interpretation universally adopted by DNS cache implementors, is that (1) bytes 65-90 are treated identically to bytes 97-122 respectively and (2) there are no other equivalences. If the wording isn't clear enough for non-implementors, perhaps it could be improved, but that wouldn't justify your false claims that DNS has problems with 8-bit names. ---D. J.
