The idea behind this lab is to give you some concrete experience with some of these concepts, so that you can better follow the lectures, and to build your intuitions about how the internet works.
Follow these steps to find out the (numeric) IP address of the computer you are on:
Question: on a WITS lab machine, what is the relationship between the last part of the Collins part of the domain name (e.g., "XX" in "cln-407-XX.willamette.edu") and the last part of the IP address?
Keep a paper or text file "log" with this information in it for your demo.
FInd at least two other computers you can use (in other Willamette locations, in your dorm or house, or perhaps in your parents house(s). Find out the IP addresses of these computers and jot them down.
Do you see any patterns relating to geographic or organizational relations? (This is an open-ended question: you may not see any patterns based on the specific computers you checked.)
The ping command allows you to test a connection to another computer, by sending packets to the destination machine repeatedly and measuring how long it takes the packets to come back. Use a command like this:
Try using this ping command on several different destination computers and compare the results:
occs.cs.oberlin.edu; does it take longer? where is this machine (see below)?
18.104.22.168(where is it?)
Having trouble copying and pasting from the command line? Use your right mouse button and choose "Mark", then select a rectangular area that you want to copy, then hit Enter (the key). Now you should be able to paste the text you copied (into your "log file" for example).
You can use either of the following web sites to check the geographic location of a machine based on its IP address:
AntiOnline IP locator
Another useful command will give you information about the route that your packets took to get to some destination. Use the command
(or traceroute hydra.willamette.edu on a Mac)
Using this tool and some of the same addresses above, answer these questions:
Try cutting and pasting Unicode text from the Word documents of the last lab into an email message to yourself. Do the Unicode characters arrive intact? Do you need to make any special changes in settings (some email programs might require you to specify a message format that uses Unicode).
Can you paste in styled text with fonts such as those in the WingDings font from the original Microsoft Word document? Do they "survive" the email process intact? (If possible, see what happens when you use a font that doesn't exist on a destination machine where you read your email: this may take a little experimentation.)
Read the and do tutorial located at the link below, then show during your demo that you can edit a Wiki sandbox page located at the tutorial to include some text of your own.
