Carolyn Duffy Marsan of Network World reports that more than 70% of IT departments plan to upgrade their websites to support IPv6 within the next 24 months, according to a recent survey of more than 200 IT professionals conducted by Network World. Plus, 65% say they will have IPv6 running on their internal networks by then, too.

Shannon McFarland compiled his list of top five misperceptions about IPv6 deployment for Network World.

These topics make very interesting reading.

Computerworld has a good article on the estimated initial costs for upgrading to IPv6 and maintaining an IPv6 presence. It also discusses some of the risks associated with upgrading servers and software to IPv6 and the potential impact on performance
that has to be factored into an organization’s migration planning.

IPv6 for Home Networking getting IETF Attention As IPv6 deployment moves from the Internet Service Providers to the Enterprise users, the next logical progression will be into the home. The average connected home today has a simple IPv4-only router which is a NAT/Firewall device. To support native IPv6 in the home, new procedures and equipment will be needed. The article below touches upon some of the challenges faced in deploying IPv6 in the home, including looking forward to the day when IPv6-enabled low-power wireless sensors are scattered about the home, in everything from alarm systems to thermostats to appliances.

In the story below, Jeff Doyle of Network World makes several good points for why Large-Scale NATs (LSNs) are bad for IPv4 – IPv6 transition.   In addition to adding another layer of NATs to those already in use, this second layer of NATs, where private IPv4 addresses are mapped to public-facing IPv4 addresses, can cause breakage for some applications.  In addition, memory allocation issues in the LSN may cause user session timeouts or conflicts.   Datatek’s IPv4-IPv6 Transformer avoids these issues by tightly coupling to the IPv4 Legacy Device.

When it comes to IPv6 support, consumer home networking gear lags far behind other devices, like enterprise equipment and PC operating systems. Most devices certified as IPv6-compliant by the IPv6 Forum are full of implementation bugs, experts say.

Timothy Winters, senior manager at the University of New Hampshire’s InterOperability Laboratory (UNH-IOL), gets calls every week from headhunters looking to hire network engineers, network architects and software developers with experience in IPv6, the looming upgrade to the Internet’s main communications protocol.
