I don't think you have understood the objective of this part of the
assignment.

You are not expected to directly query the root server yourself.  You
are to set up one host as a caching DNS resolver and then point a second
host to use this server as its DNS server.  After that, you are to use
tcpdump to track the various quries, including the query from your DNS
server to the root server.
