(10 points) What is the IP address and fully-qualified domain name of your host? Show the session that you used to obtain answers to your questions. 2. (10 points) Get the IP addresses for the following hosts: cs.berkeley.edu, www.nato.int, omsi.org, www.abc.tv, www.nasa.gov, www.lumensoft.biz, cnn.com, and mit.edu. If a host has multiple IP address and/or domain names, list them all, along with the classes of the IP addresses. 3. (20 points) Browse the IETF website (www.ietf.org), locate the citation for the latest RFC, and write down the following information about it: RFC number, title, author(s) or editor(s), date submitted, and status. 4.

(10 points) Use the traceroute command to obtain the hop count and the time taken for one-way travel of data from your host to cs.berkeley.edu and mit.edu. Show your session. 6. (10 points) Use the ping command to collect latency statistics from kosh.nku.edu to ftp.uu.net and www.google.com. Use 10 packets and report the average latency to both hosts from kosh. Show your session. Which host has the lowest latency? Why does is it lower than the other host’s latency? 7. (10 points) Download RFC #821 using the wget command. Show your session. What network applications would use this RFC? 8. (10 points) Download git-0.01.tar.bz2 from ftp.kernel.org using wget with an ftp URL. Show your session.
