Transitioning to IPv6


What has been forecast for years has finally occurred. IANA has run out of IPv4 addresses, and the Regional Internet Registries started exhausting their pools in late 2011. For organizations that must support a growing client base and an explosion of IP-enabled devices, the lack of availability of IPv4 addresses is not just inconvenient, it is an emergency.

The Need


There are a number of different technologies available to help organizations manage the transition to an all-IPv6 world while still supporting legacy IPv4 customers and Internet content. Running a dual stack network is always an option, but can be economically prohibitive because equipment vendors can charge for each network stack utilized. Tunneling technologies like 6rd and Dual Stack Lite allow organizations to run a single protocol stack on the network core and encapsulate the other protocol within it. But this approaches requires that equipment be deployed at the client site and also adds complexity to the network.

The Solution


For many service providers, NAT64 combined with DNS64 is the ideal solution. These technologies allow an organization to deploy a single IPv6 networking protocol to the client while still providing client access to both IPv4 and IPv6 Internet.

Secure64 DNS Cache is a secure, high-performance caching DNS server appliance with built-in support for DNS64, and is compatible with leading, third-party NAT64 solutions. This solution offers a number of advantages over alternative IPv6 transition technologies:

  • Reduces capital costs associated with supporting two networks
  • Reduces operating costs by simplifying network administration
  • Reduces latency compared to tunneling technologies
  • Eliminates the need for new IPv4 addresses to fuel growth
  • Eliminates the need for a second migration away from IPv4-based solutions like dual stack or 6RD
