Part 1: IP Adresses
A. determine Address Blocks and Locations
(similar to P16 in the book) Use the whois service at the American Registry for Internet Numbers - ARIN Whois/RDAP - American Registry for Internet Numbers - to determine the IP address blocks for the three universities in Berlin as well as the HTW and BHT. Hint: you may need to find out the/one ip addresses first. Caan the whois services be used to determine with certainty the geographical location of a specific IP address? Use www.maxmind.com to determine the locations of the Web servers at each of these universities.
Now try the same from home / using your private ISP connection. What can you learn about your ISP and your location using this services? (You may want to do this for each person in your team and compare the results.)
If you haven’t so far, try it with the ip for tu-berlin.de.
B. Private Addresses
