Tracerouting

So I Tracerouted from http://computer.howstuffworks.com/ to http://www.curtin.edu.au/ and it took 21 hops to get there.
According to the information on tracerouters on HowStuffWorks the three millisecond numbers show how long it took a packet of information to get from my PC to the router and back again and the average of those was 249.66 milliseconds. Finally, it also told me that Curtin's host IP address is 134.7.179.56.
