Google has always been enthusiastic about the new Internet protocol IPv6, and was one of the few companies to try IPv6 on the World IPv6 Day, in January this year. The trial run gave Google some valuable insight into IPv6, and almost after a year, Google has revealed that 95% of its network has been transitioned to IPv6 successfully.
Google’s Network Engineer Irena Nikolova discussed the implementation of IPv6 at Google, at the Large Installation System Administration (LISA) Conference this month. As IT World puts it,
Google has learned that an IPv6 migration involves more than just updating the software and hardware. It also requires buy-in from management and staff, particularly administrators who already are juggling too many tasks. Moreover, for early adopters, it requires a lot of work with vendors to get them to fix buggy and still-unfinished code.
Google’s migration to IPv6 started as a 20% project in 2008, and after four years, their goal of “IPv6 everywhere”‘ seems close. Google also devised a mechanism that allows connecting devices to acquire IP addresses, even if their operating systems do not support DHCPv6 (the IPv6 counterpart of DHCP). In addition to this, they have also developed their own address-space schemes.
This paper accompanying the presentation gives more details.
Tech giants are midway through switching to IPv6 and it is getting some fair attention at the same time. Network World is holding a conference on IPv6 today, called “The Critical Path to IPv6“. This conference will explain why IPv6 is important for your organization, and why you should gear up for it. Very soon, IPv6 will breathe life into the dying IPv4 address-space.
