No. There is no specific date when everything MUST be upgraded to IPv6 (although some organisations, including governments, have ALREADY identified target dates for their own IPv6 implementation. IPv6 and its transition mechanisms have been DESIGNED for a long period of co-existence with IPv4 and it is expected that IPv4-only systems and applications will survive for many years. However, IPv6-only systems are expected to arise and many of these users are likely to be in emerging business markets and developing COUNTRIES.

Implementing IPv6 requires planning and with IPv4 address pool exhaustion expected around 2010-2011, planning needs to start now. Network operators and administrators should already be incorporating IPv6 into their network upgrade and procurement plans.
