IO ERROR writes: An internet-draft published this month calls for an IPv6 transition plan which would require all Internet-facing servers to have IPv6 connectivity on or before January 1, 2011. 'Engineer and author John Curran proposes that migration to IPv6 happen in three stages. The first stage, which would happen between now and the end of 2008, would be a preparatory stage in which organizations would start to run IPv6 servers, though these servers would not be considered by outside parties as production servers. The second stage, which would take place in 2009 and 2010, would require organizations to offer IPv6 for Internet-facing servers, which could be used as production servers by outside parties. Finally, in the third stage, starting in 2011, IPv6 must be in use by public-facing servers.' Then IPv4 can go away.
