Some systems present distinguished names using slashes as separators.  I
assume that that's what you're running into here, that your string is
being processed as a valid RDN "CN=IPv6::2001:24:28:24" and an invalid
RDN "64".

You'll need to quote the slash.  I don't happen to know how, but my bet
would be either \/ or %2F.
