I think the answer is that is statistically very unlikely that on a single subnet, a 64-bit random number will ever be equal to any address manually configured in DHCP. Is is far more likely that by accident to ethernet cards have the same MAC address than that a true 64-bit random number will collide with another number out of a relatively small set. -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
