Homework from Class02

What do you want to learn in this class? Any specific topics?
Do you prefer to hand in homework on paper in the next class, through Blackboard, by email, to a "drop box" in AFS, or some other route? Your answer may be implicit, determined from how you hand in this assignment!
Is having class one night a week better than spreading it over two nights? Is after 5PM better than 3:30 PM?
Do you have an idea for what you'd like to do for the class project? (Don't worry, I have ideas!)
- Do you want to do the traditional packet capture, maybe some SNMP, then analysis project, or would you prefer to make an in-depth presentation on a particular topic?
What's the difference between connection-oriented and connectionless networks?
What's the difference between a hub and a switch?
What's your comfort level with the Seven Layer Model? If I start talking about Layer 4, does that take a minute to click? Would you like to see it again and again? (If you stay in networking, that'll happen anyway. Sorry. Get used to it. It's the language of the field.)
Look at your current IP settings.
1. What is it in dotted decimal?
2. What is it in dotted hexadecimal?
3. What is your gateway?
4. What is your netmask?
  1. What is your netmask in binary?
  2. How many other nodes could be local to you?
  3. What is the address range of local hosts in dotted decimal format from low to high? in CIDR?
5. How many other hosts are in your ARP table? Give me a sample (just a few lines).

Note: this question will be continued later. Sorry. Get used to it. :)

Windows uses ipconfig /all; *nix uses ifconfig -a instead. Here are my current settings for wired Ethernet:

hope$ ifconfig en0
en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	inet 152.19.145.2 netmask 0xffffff00 broadcast 152.19.145.255
	ether 00:16:cb:9d:68:60 
	media: autoselect (1000baseT <full-duplex,flow-control>) status: active
	supported media: autoselect 10baseT/UTP <half-duplex> 10baseT/UTP <full-duplex> 10baseT/UTP <full-duplex,hw-loopback> 10baseT/UTP <full-duplex,flow-control> 100baseTX <half-duplex> 100baseTX <full-duplex> 100baseTX <full-duplex,hw-loopback> 100baseTX <full-duplex,flow-control> 1000baseT <full-duplex> 1000baseT <full-duplex,hw-loopback> 1000baseT <full-duplex,flow-control> none
