About your machine.
(Mac users see the end of this section)
Open the Start Menu
In the box at the bottom of the menu type
cmd
In the list that appears, locate cmd.exe and double click it
A black window will open and you should type
ipconfig
then press enter.
What is the IP address of your machine? Hint look for IPv4 address
Here is a website that will give you your IP address:
http://whatismyipaddress.com
BUT
I got contradictory results:
WHY? Because 192.168.1.33 is not an internet address – it is an address reserved for
local networks. In this case it is assigned by my home wireless router.
You can check who owns an IP address here
http://geektools.com/whois.php
so do it with your IPv4 address.
While we are here lets test your internet connection. Enter
Ping google.com
What is the IP address of google.com?
How long does sending the message take?

For Mac Users
To get your IP address

Important: read far enough so that you DO NOT give the loop-back address 127.0.0.1
To ping

I suggest that you set the number of pings to 4
Lets go out to the internet and see how things are going
Internet traffic report
http://www.internettrafficreport.com/
Talk about what you see here. Be sure that you scroll down and click on specific regions.
Going to this level of detail is part of the question.
Note that the list of routers is only a small sample of the available routers in any region.
You are seeing a sample, not the whole internet.
WHAT IS THE POINT? Summarize what you learned from this exercise.
We can see how packets are routed over the internet.
Not always as you would expect.
Visual Trace Route
http://www.yougetsignal.com/tools/visual-tracert/
Important:
1) Use the Proxy Trace button. The service which provides the maps is located near
Aneheim, California. Thus all traces will first go from Drexel to this point.
2) Some of the nodes on the internet are large computer centers. You may see a message
make several jumps without moving as a particular computer is selected to send the
message on. Note: sometimes a node will be reported as “Unknown,” This is because
this site has an incomplete database -- it generally means that it is simply another
computer at the same location as the previous node.
3)Important: The maps can be dragged and enlarged (controls in the upper left corner of
the map) Use these to see the details of where a message travels. A good response to
these questions requires both detail and commentary. Detail should include country
names and city names, it should comment on intermediate hops.
server.
4) This website can be very slow – be patient or try later.
