One of them is a valid prefix, the other one isn't.
Well, this has gone twice through WG last call and twice through IESG review plus several directorate reviews. In the canonical format, the non-prefix bits are all zero.

The non-prefix bits are irrelevant for the prefix and the canonical format has the non-prefix bits all set to zero. I understand that you prefer 2001:db8::1/64 to be an error but RFC 6021 and RFC 6991 consider this as valid input that can be safely interpreted to mean 2001:db8::0/64. /js -- Juergen Schoenwaelder Jacobs University Bremen gGmbH Phone: +49 421 200 3587 Campus Ring 1 | 28759 Bremen | Germany Fax: +49 421 200 3103 <https://www.jacobs-university.de/> _______________________________________________ netmod mailing list netmod@ietf.org https://www.ietf.org/mailman/listinfo/netmod
