IPv6 is a suite of internetworking protocols published by the IETF in 1998, intended to replace IPv4, and provide for vastly more IP addresses, more efficient routing and greater security. Though IPv6 has existed for many years, it is only relatively recently that operators and service providers have begun preparing the ground for its widespread use, driven by a realization that IPv4 addresses are running out, and that public- and private-sector website owners are also preparing for the transition. Operators in the U.S., France, Germany and Brazil are among those now looking to move to IPv6 quickly, joining operators in Asian countries such as Japan, South Korea and Taiwan that had earlier led the way.

The volume of IPv6 traffic and the number of websites and peers supporting it is growing, with the Regional Internet Registries (RIRs) promoting its adoption, and governments in many countries mandating a transition to v6 within their own networks, including for public-facing websites. June 8, 2011, has even been designated World IPv6 Day by The Internet Society – an initiative supported by several major website owners including Google and Facebook: it aims to get operators, equipment vendors, website owners and operating system vendors testing their v6 capabilities over the same 24-hour period.

IPv4 will be around for many years – there is simply too much installed equipment with v4-only capabilities, and too many website owners that will change to IPv6 only when it becomes essential (for instance, when they notice that they are losing customers). But interest in the IPv6 capabilities of CPE is rising rapidly as ISPs' ideas about how to managed v4-to-v6 transition become clearer, and standards bodies' and industry forums' CPE specifications become more widely promoted and adopted. The transition has started, and IPv6-capable routers, modems and gateways are appearing in homes around the world in readiness for the change.

IPv6 will be a tricky sell to consumers, as there is little benefit to the end user. What ISPs really need from their CPE vendors is help to transition from IPv4 to IPv6 seamlessly, at the lowest cost and with as little disruption as possible. There is the potential for service disruption and noticeably reduced performance from the Internet caused by some of the technologies required. CPE vendors are working hard to support ISPs' efforts to mitigate these challenges.

Residential CPE Vendors Gear Up for IPv6 looks at how operators are responding to the drivers of change to IPv6, and how they are asking for help from their suppliers of CPE. It reviews the options for managing the transition (with a focus on DSL rather than cable networks), including the use of techniques to prolong the life of IPv4, and tunneling IPv6 traffic through IPv4 networks and vice versa. It reviews the way that CPE vendors are building IPv6 capabilities into their equipment, and compares their approaches. Finally, it profiles eight of the leading vendors of IPv6-capable CPE.

There are few benefits of IPv6 for the end user, and an IPv6-capable gateway or router offers nothing significant by way of increased performance or functionality over existing products. Because of this, most CPE vendors have been slow to develop and promote the specific IPv6 capabilities in their products, unless requested to do so by their service provider customers: The networks and the websites visited by users must be running IPv6 before there will be a strong pull from users for IPv6-capable CPE. There is also a fragmentation of v6 capability in CPE: some devices sold to (or through) some service providers will have some v6 capabilities; others will have different capabilities.
