Network World's LANs & Routers Newsletter, 07/05/07 IPv6 migration needed By Jeff Caruso I mentioned last time that Cisco Subnet blogger and IP expert Jeff Doyle had run a series on the looming IP address crisis and the need for IPv6. After establishing the case for migrating, he's starting a series on how to actually move to IPv6. Doyle first raised the issue by looking at how IP address allocation is trending upwards. He then pointed out that some IPv4 addresses are likely to be held in reserve, meaning that the available address space could run out in 2009, which is going to be here faster than you might think. Now, you may be one of the many out there wondering what the business case is for IPv6. Doyle says there isn't one, at least not in the form of a profitable new service or a new "killer app." He writes: "The IPv6 business case is about capacity and survival. The cool new stuff comes after we have networks that can accommodate it." Manage Insider Security Threats Experts say 75% of security threats come from inside your organization.

Some folks have been talking about the need for IPv6 for a long time. Doyle says he is one of them, having been an advocate of IPv6 for eight years. So you might be tempted to label him as a Chicken Little. But the numbers seem compelling. And if he's right, preparations for moving to IPv6 need to start happening now. Doyle this week talks about the need for a plan and promises more info about how to go about a transition to IPv6. Let him know what you think.   What do you think? Post a comment on this newsletter
