Module 1 - Internet Tools

I thought that this excersise was interesting. I've always known that routers were used to shift data around the Internet, but never really had it put into perspective until seeing this site. It took 21 hops to contact the curtin server and the average time was about 2sec. It had three time outs and from further investigation this means that the packets were having some kind of problem getting to the target system and/or back.

When using my mac terminal to traceroute the curtin.edu.au server I had the same problem with timeouts but this time they never ended. It also seemed toBlockquote get three extra servers after the gw1.er1.curtin.cpe.aarnet.net.au server. Could this be because of my ISP?

The IP address of curtin.edu.au is 134.7.179.53 and as you can see on the mac traceroute, it never even reaches this server.
