Yahoo IPv6 upgrade could shut out 1 million Internet users
Yahoo is forging ahead with a move to IPv6 on its main Web site by year-end despite worries that up to 1 million Internet users may be unable to access it initially.
Yahoo's massive engineering effort to support IPv6 -- the long-anticipated upgrade to the Internet's main communications protocol -- could at first shut out potential www.yahoo.com users due to what the company and others call "IPv6 brokenness.''
Yahoo has been one of the most vocal Internet companies to express concern about industry estimates that 0.05% of Internet users will be unable to access Web sites that support both IPv6 and the current standard, IPv4.
