3. Mobiles IPv6 Networks in 2015
• Deployment is progressing globally and we are now seeing some
consumer networks with IPv6 deployed.
• Telstra has been testing for some time, and is also planning to launch
IPv6 to consumers shortly.
• There are common issues that have been identified which require
discussion and consideration with other carriers to ensure the growth
of IPv6 usage continues in Mobile environments.
• Why is it important to move to IPv6?

4. Mobiles IPv6 Networks in 2015
• Public and Private IPv4 address runout
• Regionalisation and NAT444?
• IPv6 Single Stack / Dual Stack?
• Operational and Design complexity
• Consolidated networks
• Future-Proof
• How will you ensure your network is ready for future technologies
without IPv6?

5. Mobiles IPv6 Networks in 2015
Each carrier has their own unique requirements for deploying IPv6
• Dual Stack
• Single Stack
• NAT64 + DNS64 + 464XLAT
• Hybrid
• NAT64 + DNS-HD + 464XLAT

6. Questions for the Future
• Continued 464XLAT support on UEs
• Roadmap to transition to Single Stack for Dual-Stack only UEs
• CDN native IPv6 local support
• NAT64 ALG improvements
• Does your PLAT understand a CLAT translation is occurring?
• International Roaming for Data will be stuck on IPv4
• IMS/VoLTE supports Dual-Stack. But why would you use IPv4
addresses?
• What about IMS/VoLTE RAVEL

7. Disruptive Technologies?
Will these change the way you think about how important IPv6 is or how
your network architecture will change?
• Software Defined Networking
• Network Function Virtualization
• Virtual Evolved Packet Core
• Internet of Things

8. Conclusion
There are operators who have launched commercial IPv6 services
already. Each operator must decide their own path – there is no single
universal answer on how this can be done.
