IPv6 is the evolution of the Internet Protocol and was created in the late 1990s when it was clear that the then-current version (IPv4) would run out of available addresses soon. Soon after, software was converted to handle IPv6 and the all service providers began offering IPv6 connectivity. Right? Not really. It's been a chicken-and-the-egg problem: no apps supports it, so services don't support it, so no apps supports it. This session will go over the basics of IPv6, how it differs from IPv4 and what client and server developers should be aware of. It will go over the basic socket API and provide instruction for developers on how to write software capable of both IPv4 and v6, seamlessly. It will then discuss how IPv6 and certain features not available in IPv4 can be used for interesting functionality, but also what admins would want to be aware of to protect their systems.
