Badly. Next thing is IPv6 NAT, when people try to "cascade" access points/routers within their home network. Like it or not, CPEs MUST get more than /64, and MUST support downstream prefix delegation. Last time I checked, Free was not assigned the whole IPv4 address space. I assume they don't want to provide the Rapid Deployment service to customers of *other* ISPs. So while they do only have a /32 IPv6 prefix, they don't need to burn 32 further bits to keep track of each of the IPv4 address of each of their customers. Storing the 24 lower order bits should be sufficient. And this leaves 64-32-24=8 rouable bits per customer. -- Rémi Denis-Courmont http://www.remlab.net/
