Actually, a /64 always falls on a nibble boundary. As does a /56. Regardless of left-most, center-most or right-most allocation methodology, future scalability concerns, etc. No bits lost, yes? /TJ -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
