This is my second blog entry on the topic of the 'digital divide'. I would have posted it earlier but I haven't been able to access wordpress.com from home.
There is also an introductory post from a few weeks ago.
Yahoo has made public its proposal to hack the domain name system (DNS) so as to resolve issues with migrating to IPv6 from IPv4.
Internet protocol version 4 (IPv4) was the first widely deployed version of IP that supports 32 bit addresses (equating to 4,294,967,296). The issue of exhausting the 32 bit address allocation was identified in the 1990's, prompting the development of IPv6. IPv6 supports 128 bit addresses, obviously offering a more expansive address system.
The article claims that a 'significant percentage of internet users have broken IPv6 connectivity'. Yahoo thus proposes to switch users to IPv4 connectivity once detection of broken IPv6 connectivity is realised.
Yahoo will forward its proposal to the Internet Engineering Task Force, however questions of DNS trust and security will surely be the two topics of debate in testing this proposal.
