Scaling IPv6 at Fastly
IPv6 has often been characterized by those looking to minimize the FUD surrounding deployment as "96 more bits, no magic." In fact, minimizing the differences afforded by the 96 bits undersells the proposition of a new expansive address space. In this presentation we describe how fastly leverages IPv6 address space, as well as how we retrofit concepts gleaned from our IPv6 experience onto the legacy IPv4 network with it’s necessarily more limited resources. This talk covers changes that affect provisioning, security, dos protection, and availability.
