(Hands-On Activity) Use the online dig tool (http://www.digwebinterface.com, described in the PLE "DNS Example Using digwebinterface.com") to act as the local authoritative server for a client trying to resolve the IP address of www.cs.odu.edu. (This means that you must make successive requests to name servers until you receive an A record for www.cs.odu.edu.) Check the "No recursive" option, specify the appropriate name server for each request using the "Specify myself" option, and do not use the "Trace" option. For each name server that you query, enter its hostname or IP in the "Specify myself" box. You may start with one of the following root name servers: d.root-servers.net or a.root-servers.net. For each query, indicate the dig command used (do not include the response received). Also give the final answer (IP of www.cs.odu.edu).
