Suppose there is one DNS server for every domain in the following figure, where robot, linda, pc24, flits and fluit are hosts, and the rest are domains.
Suppose pc24 wants to know the IP address of host robot.ai.cs.yale.edu, and issues a DNS request. In the worst case, how many DNS servers will be queried? Who are they? Please use the complete domain names (e.g., jp.ac.keio.cs) to identify those DNS servers. Also explain the procedure of how the IP address of host robot is found.
