    Microsoft Execs Expressed ‘Shock and Disbelief’ at Internet Address Shortage

    Microsoft encountered a shock earlier this year: Networking issues suddenly cropped up across the company's sprawling Redmond, Wash., campus, causing headaches for engineers and pushing the company toward substantial expenditures.

    The problem was a side effect of the imminent demise of Internet Protocol version 4, a digital communications method that has kept the Internet humming since the early 1980s. IPv4 specifies Internet addresses that are like telephone numbers (distinct from the familiar .com, .org, and .net domain names). These numerical codes are used behind the scenes to uniquely identify any connected device.

    IPv4 defines 4.3 billion such addresses ...

    1. During the first half of 2015, Microsoft exhausted the RFC1918 addressing space due to the explosive customer growth of our cloud and enterprise products and solutions.
    2. So now we're even overlapping . . . and we've had conflicts.
    3. With help and insight from our engineering staff, we recognized the problem quickly and moved into the action of making the shift from IPv4 to IPv6 so that we didn't run into problems internally or externally.
