|   If we require a solution (even a short-term one) to address 
|   this fully,
|   then yes, this is a problem. However, I think we can leave 
|   this problem
|   unsolved for now as there doesn't seem to be a good reason for an

News flash: we left this problem unsolved when we did CIDR for IPv4.
It's now an issue.  It needs to be addressed if IPv6 is to succceed.
