How large should an address be to define a single device on any network in the world?
What will be an ideal response?
The real answer to this comes down to the number of domains, but it should prompt a discussion among the students to get them thinking about how to define an addressing scheme to be big enough to capture any device uniquely.Push the discussion so that it focuses on how to define countries, regions, localities, networks, and subnets.The answer that is discovered should be essentially inconsequential because this is a thought exercise rather than an explicit one, but it should be larger than or equal to 32 bits.
