> Hallo,
> as the editor of RFC2163 it just came to me a "possible" encoding
> problem, or at least something to consider carefully to avoid problems, that
> in section 4.2.1 IA5-Printablestring to <alphanumhyphen> mappings, there
> CAN be as a result, domain names where there is the "--" string. These
> domain names (see the example in page 12, "O--h-123-h-b") are alway under
> a special second level domain "X42D" (i.e. X42D.<ccTLD> ), but maybe it
> is worth to add a note to the encoding documents in order not to have
> confusion in implementers.
>
> Maybe it is just not needed, but you never know...

> just my two cents...
