Not enough to address the problem, in fact, as early as 1990, IETF (Internet Engineering Task Force, established in late 1985, is the world's most authoritative Internet technology standardization organization) began planning the next-generation protocol IPv4.
Yes, that is touted as "to every grain of sand on Earth is assigned an IP of IPv6 ."
