Limelight Networks(R) Introduces Industry's First Content Delivery Service With IPv6 Support


TEMPE, Ariz., June 15 /PRNewswire-FirstCall/ -- Limelight Networks, Inc. (Nasdaq: LLNW) today introduced the industry's first content delivery service with Internet Protocol Version 6 (IPv6) support. The company announced this upgrade of its global distributed computing platform to the next-generation protocol during a panel presentation at NANOG46, the annual meeting of the North American Network Operators' Group, held this year in Philadelphia, PA.

"Content consumption is moving beyond just the browser to a new class of Internet-connected devices, as consumers are accessing their favorite media wherever and whenever they want. As one of the first CDNs to offer IPv6 services, our platform is now ready to deliver content to that next generation of always-connected devices," said Nathan Raciborski, co-founder and chief technology officer, Limelight Networks, Inc. "We're pleased to be leading the industry in offering IPv6 services, and look forward to working collaboratively with our customers and partners to deploy IPv6 applications across our worldwide network platform."

Limelight Networks' IPv6 capabilities include:

    --  Ability to offer dual-stack (IPv6/IPv4) or IPv6 connectivity at
        company-owned locations
    --  -/32 allocations from the American Registry of Internet Numbers (ARIN),
        Asia-Pacific Network Information Centre (APNIC), and Reseaux Internet
        Protocol Europeens (RIPE)
    --  Full IPv6 transit routes from multiple providers
    --  Full IPv6 Domain Name Services (DNS)
    --  IPv6 peering at v6 enabled-exchanges
    --  IPv6 (dual-stack) capable from any transit or peering or customer origin
        ingress to the edge
    --  Customer and end-user IPv6 interface for existing or new IPv4 content

The IPv6 protocol designed by the Internet Engineering Task Force will gradually replace the current protocol widely used on the Internet, Internet Protocol v4 (IPv4). The 32-bit IPv4 address space for devices is rapidly being depleted, an issue resolved with the 128-bit address space allowed for in IPv6. The IPv6 protocol also adds improvements in areas such as bandwidth efficiency, routing, and network autoconfiguration. Limelight Networks will run IPv4 and IPv6 simultaneously across its entire network platform.
