A talk I gave at Vermont CodeCamp 11 on September 28, 2019. ---- Abstract ---- How well do your applications or websites work over IPv6? As the world runs out of IPv4 addresses, new mobile networks are being deployed as “IPv6-only” with IPv6-to-IPv4 gateways at the edge of those networks. The result is that apps and sites that work natively over IPv6 will be faster for users than apps and sites stuck on only IPv4. Many leading services have already made this transition, and Apple now requires IPv6 for all apps in their AppStore. In this session, you’ll learn about tips and tools to successfully migrate your applications and sites to work over both IPv4 and IPv6. Bring your questions and concerns - and sharing of success stories would be welcome, too.]]>

Taking place in networks, board rooms and legislatures, the battle will determine how we all communicate and what opportunities will exist. Will telecom support innovation? Will it be accessible to all? Will it give us the level of security and privacy we need to have the open, trusted Internet? Or will it be restricted and limited by corporate or government gatekeepers? The rise of voice-over-IP has fundamentally disrupted the massive global telecommunications industry, infrastructure and policies. Open source software such as Asterisk has been a huge driver of that disruption and innovation.. but now what? What role do platforms such as Asterisk play in this space? And what can be their role in a telecom infrastructure that is now mobile, increasingly embedded (Internet of Things) and more and more using proprietary walled gardens of communication?

With the recent buzz around World IPv6 Day and the exhaustion of top-level IPv4 address allocations, organizations are starting to seriously look at exactly what is involved with migrating to IPv6... and asking questions about what this means for all their VoIP and Unified Communications systems. Given that the reality is that a "IPv6-only" world is a distant future, questions are particularly being asked around how those telecommunications systems will work during the transition period from IPv4 to IPv6. In this session, Voxeo's Dan York will explore where IPv6 and telecom play nice together and where there are serious minefields that may restrict telecom from working over IPv6 In this session, Voxeo's Dan York will explore where IPv6 and telecom play nice together and where there are serious minefields that may restrict telecom from working over IPv6
