Get SIX Appeal! An IPv6 CGNAT Starter Kit from Juniper Networks

While the internet community is busy planning the IPv6 World Launch by June 2012 many service providers in Europe are still debating their IPv6 strategy. Internet service providers (ISPs) and enterprises are upgrading their networks to IPv6, they are likely to incur costs running into hundreds of millions of dollars, according to a recent report from IXIA.


Looking at a recent report from Alexa (Comcast’s IPv6 monitor), on the top 1 Million sites analysed less than 1% are reachable natively on IPv6. We all know that the IPv6 World launch is not going turn all Internet sites into IPv6 overnight, but hopefully it will accelerate its adoption among the popular ones.


What will be the effects?


  • The native IPv6 subscribers will get a better quality of experience to these sites, eliminating the latency of the address translators. 
  • Service Providers with an existing IPv6 subscriber base will reduce the pressure to its Carrier Grade Network Address Translators (CGNAT). However, CGNAT will still be needed  to provide connectivity to the IPv4-only sites .
  • This might add one more reason to accelerate the adoption of native IPv6 in the access networks.
  • In the unlikely case of the raise of IPv6-only services, subscribers might start asking for IPv6 connectivity or at least get access though CGNAT.

As we can see the CGNAT seems to be a common component in any IPv6 transformation or IPv4 address conservation strategy.  With this in mind it is important to make provision for CGNAT.


The Carrier Grade Network Address Translation (CG-NAT) infrastructure facilitates Service Providers sharing less public IPv4 addresses with more subscribers. And at the same time enabling IPv6 connectivity to prefer IPv6 connectivity vs IPv4 connectivity when possible, for example, Dual-Stack+6rd, DS-Lite… acting as a gateway between IPv4 and IPv6 networks in a scalable way, that is NAT64.


CGN serves as the building block in any IPv6 transitional strategy and particularly if the service provider needs to tackle IPv4 depletion at the same time. To learn more about the role of CGNAT and what it means for your business, you might want to attend Juniper’s Webinar (Design Considerations for Next-Generation Network Addressing Solutions) or the IPv6 series on demand, where we share our knowledge on IPv6 and what you need to do to make your network IPv6 compatible.




At the V6 World Congress, at Juniper Networks booth we are presenting  the SIX Appeal  special offer for service providers, it consists of a CGNAT Starter Kit based on the MX Series along with professional services. For more details, go to




Juniper Networks has a leading CGNAT Solution based on MX or SRX series. A large list of service providers in Europe have already deployed Juniper Networks MX CGN solution. If you would like to find out more about these deployments, then please get in touch.


I can certainly recommend you to get CGN quickly and smoothly up and running in your network and take advantage of our experience with confidence!
