Module one. traceroute

Late at night and I've just discovered traceroute and ping.
Reading the Howstuffworks site was very helpful, rather than diving in and winging it.
Using the site http://centralops.net/co/ I was able to tracerout to curtin however the ip address was different to the 'correct answer in the self test. It appears from the discussion board that others have experienced the same.
As shown below it took 22 hops between centralops and curtin with an average time of 246 milliseconds.
