With the explosion in the number of smartphone users and the number of Internet addressable devices like tablets there is indeed a strong momentum building towards IPv6 migration. Datacenters and cloud infrastructures are now sprawling with countless virtual machines on the same servers that were once manageable with a set of IPv4 address; Now IPv6 seems like a no brainer. But, a recent conversation with a customer about IPv6 migration revealed that IPv6 with all its technological benefits versus its predecessor IPv4, even today lacks the simplistic appeal. There are elements like network address translation that have not been out there long enough to mitigate the perception of complexity, delaying deployments and faster migration into IPv6.

The secret of migration to IPv6 lies in the seamless transition for both end users and administrators alike. One of the key challenges within the cloud is the elasticity and dynamic nature of server allocation with Application Delivery Controllers (ADCs). With IPv6 not being available in all parts of the world it necessitates the interim solution requiring simultaneous IPv4 and IPv6 addressing. Also being able to have both legacy IPv4 and new IPv6 infrastructures operating side by side allows for a more smooth transition.

Deploying with IPv4 and/or IPv6 addressing facing the internet and a combination IPv6 and IPv4 addressing within the datacenter requires a fully capable v6-v4 Network Address Translation proxy that can handle millions of user connections for their corresponding applications, all while simplifying the transition. The last of the IPv4 addresses are being auctioned off as we blog about IPv6. Cable giants like Comcast have already made the shift to IPv6 and are leading the charge. World IPv6 day is June 8th 2011 when many vendors and service providers will flip the switch and go IPv6 for a day; is your IT infrastructure IPv6 ready ?
