Internet detective work

Use nslookup to answer the following:
  1. What is the IP address of www.google.com?
  2. What is the domain name of 18.7.22.83?
  3. What is the IP address of the DNS server that found the answers?
  4. What is the name of the technical contact for 18.7.22.83? (Use whois at dnsstuff.com)
  5. I tried to use nslookup to find the externally routed IP address of sws.csudh.edu, but, because I was on campus and behind the firewall, I got the internal, non-routable IP address: 
    C:\>nslookup sws.csudh.edu
Server:  it-dc01.toronet.csudh.edu
Address:  10.84.0.11

Non-authoritative answer:
Name:    sws.csudh.edu
Address:  10.26.0.157
    How could I get the externally routed IP address of sws.csudh.edu?
Turn in listings of your nslookup sessions along with the answers.
