Vint Cerf, one of the web’s founding fathers, is leading a global campaign to encourage web service providers and IT managers to switch from the current system, IPv4, to IPv6. The new standard offers many trillions of new web addresses, but cannot be accessed from modems and routers that only use IPv4. It is likely, however, that most of the changes needed will take place without consumers losing access to any part of the web because they will be part of the standard software and hardware upgrade cycle.
Writing on the Google Blog, Network Engineer Lorenzo Colitti said that “Google has been supporting IPv6 since early 2008, when we first began offering search over IPv6. Since then we’ve brought IPv6 support to YouTube and have been helping ISPs enable Google over IPv6 by default for their users. On World IPv6 Day, we’ll be taking the next big step. Together with major web companies such as Facebook and Yahoo!, we will enable IPv6 on our main websites for 24 hours.”
He added, however, that “Our current measurements suggest that the vast majority (99.95%) of users will be unaffected. However, in rare cases, users may experience connectivity problems, often due to misconfigured or misbehaving home network devices.”
