The drive to IPv6, the newer Internet communications protocol, appears to be driven by major networking vendors. Their contention is that we’re running out of IPv4 network addresses. They’ve got the Obama administration behind them, and the White House is pushing to have all federal departments and agencies enable the use of native IPv6 by the end of 2012 as part of an overall move toward this newer Internet communications protocol. However, the feds will continue running both IPv4 and IPv6 simultaneously into the foreseeable future to ensure interoperability.
