This is all great and dandy, but then why does it appear that anybody with a cable modem this side of the sun are using static IP's. Granted that the Nic probably didn't allocate the current /8 (or the next one), but I don't see any (and didn't see any prior) 'investigation' to make dynamic allocation possible (or using RFC1918 addresses). Are they looking at DHCP or RFC1918 as a solution for their userbase ? While we're here pulling our teeth on returning addresses and not allowing static IP's for a combined user base of several million internet users, a group of users with less than 50K (correct me if I'm wrong here) and no track history of rwhois/swipped addresses gets gets /8's for allocation to a static IP userbase.......
