The IPv6 Forum, a global consortium of research networks with 160-plus members, including Cisco Systems, HP, IBM and Sun Microsystems, recently launched the IPv6 Ready logo program. (In 1992 the Internet Engineering Task Force initiated the effort to solve the shortage of addresses of Internet Protocol version 4 (IPv4). SIPP (Simple Internet Protocol Plus) was chosen from several IP candidates and adopted in 1994 and named the Internet Protocol version 6 (IPv6) in 1995 when a basic specification was established.) .
