Limelight Networks said today that it’s the first company to introduce IPv6 support into a content delivery service.

With the number of IPv4 addresses rapidly dwindling, large service providers like Comcast are looking at IPv6 as a way to connect the various devices on their networks. IPv4 uses 32-bit address space, while IPv6 has 128-bit addresses.

IPv6 is supported by the cable industry’s DOCSIS 3.0 specification.

"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 for Limelight Networks.

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)
  • Customer and end-user IPv6 interface for existing or new IPv4 content
