With the exhaustion of IPv4, organizations will soon have to migrate to IPv6. While there isn't a hard deadline like with Y2K, the longer IT puts off IPv6 migration, the more difficult connecting to Internet and partner resources will become. IPv6 isn't rocket science, but there are a number of decisions that IT will have to make before and during the migration. In this tech center, we will dig into the architectural issues that IT will need to address from designing the IP layout through to migrating to supporting services like DHCP and DNS.

Can SIP and IPv6 Co-Exist?
Enterprises need to make transition plans for SIP endpoints that will have to be upgraded or replaced within the next five to seven years, as they move to a dual-stack environment. Learn more about getting SIP and IPv6 to work together.
Cisco Visual Networking Index Predicts More Video and Devices
According to the latest Cisco Visual Networking Index, there will be much more video by 2016, which will increase bandwidth and quality-of-service demands. The growth in tablets and smartphones will lead to new management and security challenges.

IPv6 Is Coming. Time To Get Prepared
August 24, 2011 04:01 PM
Posted by Mike Fratto
IPv6 is coming. Sooner or later, you will be deploying IPv6 on your network, data center, or co-lo servers. It may be a few years off--longer if your ISP has a well thought out transition strategy in place--but IPv6 is different enough that you can learn the ins and outs on a smaller network before you have to deploy it widely. If you are looking for resources, start there. If you have a good resource you want to share, send me an email and I will check it out.

Vint Cerf's Internet Safety
June 15, 2011 08:10 AM
Posted by Mike Fratto
At the Internet Society INET conference, there was wide-ranging discussion on a variety of topics, from Net neutrality to privacy. A highlight was Vint Cerf's keynote in the afternoon. He focused on the importance of safety mechanisms for those using the Internet--safety in terms of being protected from abusive behavior and safety in terms of the ability to speak freely and, where and when needed, remain anonymous. These are big issues in the international theater.

Six Reasons It's Blame IPv6 Day

As far as I am concerned, it's not World IPv6 Day. It's Blame IPv6 Day. This is a good opportunity to take any new technology (OK, IPv6 is not new, but it might as well be) and use it as the whipping boy it deserves to be. It's IPv6's turn. So, lets get started!

We Are IPv6 Ready!
May 03, 2011 02:55 PM
Posted by Mike Fratto
I am happy to say that Network Computing is now IPv6 ready. That's a pretty neat leap for us, and when I get around to setting up a tunnel broker from my home office, I will be enjoying some IPv6 goodness. The neat thing about being IPv6 ready is that whether you are coming from an IPv4 or an IPv6 network (and, frankly, you won't know or care which), you will still get to the same place. Making Network Computing available via IPv6 means you will get to us no matter where you are. Congrats to our IT team who got us there.

IPv6 And DNS On The Interopnet
February 18, 2011 07:00 AM
Posted by Mike Fratto
The early planning work on Interop is moving along. Glenn Evans, who is managing the Interopnet and characterizes the position (with tongue firmly planted in cheek) as "benevolent dictator," and the rest of the NOC team have the daunting task of building and maintaining a production network for attendees and exhibitors, as well as providing the infrastructure to demo new technologies. At this early stage, work is being done to figure out what to offer to the show attendees and exhibitors. "If Interopnet builds it, users will come" is not a given. Here is where they are now.
