Under the theme, "The Future is Forever," ISOC's World IPv6 Launch on June 6, 2012 marked the largest industry commitment to and deployment of IPv6 in the history of the Internet. Participants of World IPv6 Launch included major ISPs, web companies and home networking equipment manufacturers from around the world.

In order for home router vendors to participate in World IPv6 Launch, ISOC required that the companies enable IPv6 'on by default' through their range of home router products and successfully complete the IPv6 Ready CPE Logo Interoperability testing at the UNH-IOL. Thus, in preparation for the launch, the UNH-IOL hosted its fourth home router test event allowing vendors to test the interoperability of their IPv6 implementations and satisfy the requirements for World IPv6 Launch participation.

During the UNH-IOL IPv6 CE Test Event, participants tested their IPv6 implementations against the IPv6 Ready CPE Logo Interoperability test specification using common interoperability test beds, including: Ethernet and DOCSIS networks, as well as DSL Wide Area Networks (WAN). Figure 1 below shows the network topology used during the test event.

Participants included both returning home router vendors that participated in previous UNH-IOL IPv6 CE interoperability test events and vendors that brought products to test for the first time. Vendors that attended previous events were validating updated implementations to meet the latest requirements in IETF 6204bis, such as DHCP SOL_MAX_RT. Those vendors attending the event for the first time were able to leverage other vendors' previous experience and resolve implementation issues more quickly than during the past events. This allowed them to proceed beyond the basic testing and validate more advanced IPv6 features.
