http://www.caida.org/IPv4space/ (from hwb who didn't want to post cause the text isn't really ready but i figured nanog folks wouldn't read the text anyway and the pictures speak more to than the text will anyway) this probably belongs on big-internet or ipv6 some other list i'm not on and don't know if exists anymore anyway so delete/forward if you want k/hwb ps yes it would be nice to have animations of this in real-time throughout the last few years but we don't have such historical data so oh well comments/feedback welcome anyway
