- Slots can now require each student to check-in from a unique IP address
  when using a particular slot for a specific resource. The IP address of
  the student's computer is then tied to that student's access to the resource
  thereafter, until the end date of the slot.
  (Intended use case is high stakes online testing where students are using
  computers with statically assigned IP addresses).
