Name-Server Homework

1. Use nslookup on Unix to find out
   • the mail server for your machine
   • the IP number for www.ics.hawaii.edu
   • the canonical name for www.ics.hawaii.edu
2. Start nslookup with no arguments, set querytype=SOA, and look up ics.hawaii.edu. Look at and try to understand the DNS parameters for the root of the ICS domain.
3. Look at /etc/resolv.conf. For each DNS server listed there, determine what its domain name is (using nslookup) and whether it's on the local ICS net (using traceroute).
