problems making Certificate Request

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.
