You beat me! But you missed two! draft-ietf-zeroconf-ipv4-linklocal-01.txt draft-perkins-manet-autoconf-00.txt These take 169.254/16; this is the IPv4 stateless autoconfiguration that Windows uses, if you plug a number of Windows boxes together on a network without a DHCP server. The network addresses are reserved as "link.local". I realize that neither is ratified to RFC status, but Windows already uses it, so there's no reason to shoot yourself in the foot unnecesarily.
