Juniper Networks to Participate in World IPv6 Day, June 8, 2011

Juniper Networks (NYSE: JNPR) has announced that it will participate in "World IPv6 Day" on June 8, 2011, a one-day "test drive" of websites offering IPv6 support being sponsored by the Internet Society (ISOC). In this effort, Juniper is furthering its long-standing commitment to ensure its customers continue to be fully prepared for a transparent transition to the new IPv6 protocol to meet their respective market needs and business conditions.

World IPv6 Day will offer a global-scale test flight of IPv6, where major web and networking companies and other industry leaders will enable IPv6 on their main websites for 24 hours. One key goal is to allow participants from all parts of the global Internet community to work towards the common goal of enabling IPv6 at a large scale with minimal disruption; another critical goal is to further promote the awareness of effective IPv4-to-IPv6 transition strategies and the ability to make that transition as seamless as possible.

"Last week's anticipated announcement from the Internet Assigned Numbers Authority [IANA1] that the remaining large IPv4 address blocks have now been assigned has long been expected, and should not be misconstrued as alarming in any way—we believe the global Internet can continue its robust growth without interruption," said Alain Durand, director of software engineering, Juniper Networks Infrastructure Products Group. "Juniper Networks has been assisting its service provider and enterprise customers with a continuum of IPv4 exhaustion solutions, IPv6-enabled products and IPv4/IPv6 coexistence strategies for many years. Our participation in World IPv6 Day represents yet another extension of the IPv6 support we've delivered throughout our switching, routing and security solutions families, to now address our public website."

IPv4/IPv6 Coexistence

Juniper Networks has invested significantly in developing a broad suite of technologies and solutions that help customers meet IP addressing needs while building out IPv6 networks as rapidly as their markets and services require. With most of the world's Internet content addressed via IPv4 for decades to come, Juniper has continued to offer its customers support for robust NAT solutions, including Carrier Grade NAT (CGNAT) to ensure continued access to IPv4 devices, endpoints and content.

"The vast majority of the world's Internet content is addressable via IPv4," stated Michael Howard, principal analyst, carrier and data center networking, at Infonetics Research. "It's clear that the IPv4-to-IPv6 transition will be a long, but very manageable process."

"IPv4 address depletion is an important and long-awaited inflection point in the continuing history of the Internet," continued Durand, who is scheduled to discuss IPv4/IPv6 issues at the V6 World Congress in Paris on February 9th.

A leader on IPv6 issues since 1993, Durand is the inventor of the Dual Stack-Lite (DS-Lite) network address translation (NAT) solution to allow IPv4 and IPv6 addressing to coexist on carrier networks and has authored numerous Request for Comments (RFCs) and Internet-Drafts. He now serves as the co-chair of both the IETF Softwires and Port Control Protocol (PCP) working groups, which focuses on how applications will evolve to accommodate IPv4 address exhaustion and IPv6 address adoption.
