alphadogg writes: In a project that has taken longer than company engineers anticipated, Google is rolling out IPv6 across its entire internal employee network. Google network engineer Irena Nikolova discussed the company-wide implementation at the Usenix Large Installation System Administration conference, being held this week in Boston. From the experience, Google has learned that an IPv6 migration involves more than just updating the software and hardware. For early adopters, it requires a lot of work with vendors to get them to fix buggy and still-unfinished code. "We should not expect something to work just because it is declared supported," the paper accompanying the presentation concluded.
