IPv6: Dual-stack strategy starts at the perimeter

We are in an awkward point in the history of the Internet. IPv4 address depletion has occurred yet we expect to use IPv4 for the next 15 to 20 years. Organizations see two paths before them. One alternative is to use continue to use IPv4 and expect to use multiple layers of network address translation (NAT) for many years to come. The other alternative is to start to use IPv6, however, the majority of enterprise organizations and content providers have not embraced the protocol.

Test of ADCs

U.S. federal organizations should be working on meeting the September 2012 Office of Management and Budget (OMB) mandate to IPv6-enable all government Internet-facing web applications. The glacial speed of the federal government combined with government budget issues makes it difficult for them to meet "yet another unfunded  IPv6 mandate".

Most enterprises have ignored IPv6. They believe they have plenty of IPv4 addresses for their own needs and that they do not have a need for IPv6. The global economic downturn has caused IT organizations to "do more with less" and they have less time to learn and deploy new-fangled technologies like IPv6. Even though IPv6 has been standardized for many years, there is a general lack of knowledge and experience with IPv6 and now many enterprises are starting to realize the position they are in. Furthermore, the vast majority of organizations are confused about how to start planning for IPv6.

Warning: Tips for secure mobile holiday shopping

I’m dating myself, but I remember when holiday shopping involved pouring through ads in the Sunday paper, placing actual phone calls from tethered land lines to research product stock and availability, and actually driving places to pick things up. Now, holiday shoppers can do all of that from a smartphone or tablet in a few seconds, but there are some security pitfalls to be aware of.
