Re: Issues encountered with assigning all ones IPv6 /64 address? (Was Re: Issues encountered with assigning .0 and .255 as usable addresses?)

IPv4 addresses ending in .0 and .255 can't be used either because the
top and bottom addresses of a subnet are unusable.


Only true if speaking of /24, but with the appearance of CIDR 19 years
ago, this is not true anymore The .255 and .0 in the "center" of a /23
are perfectly usable see an earlier post
