Charter for Working Group The IOTOPS Working Group is chartered for the discussion of operational issues related to Internet of Things (IoT) devices, in particular related to device onboarding and lifecycle management.

IoT has a rather nebulous definition with different meanings for different people.

For the purposes of this WG, its focus is on devices that

are networked, either to the Internet or within limited administrative domains

have a very limited end user interface or no end-user interface at all

Either URI should be removing the [], or Addrinfo should be accepting it. Given that Addrinfo is just getaddrinfo(3), and it does not peel off the [], I think the fault is URI.
