@Max, the issue of IPv6 address size is actually not one to be glossed over lightly. The definition of DNS getHostInfo calls return IPv6 *before* IPv4 addresses accroding to the RFC. These addresses are dynamically allocated in the spec. If I simply send a few thousand DNS responses to the device following a request, I can exhause device memory (DoS attack). Then the user is "supposed" to remember to free the allocated memory using another call. One missed deallocation and you've got a substantial memory leak.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
