A student collected a packet trace on its DNS resolver while running the following command:
dig -t AAAA www.computer-networking.info
This trace was collected with a resolver that does not store any record in its cache. Can you reorder the packets of this trace by looking and the succession of the types of DNS requests starting from the root ?
