Internet Tools - Traceroute Task

What to do

For ease of use, and because free versions of internet tools are constantly changing this task only requires you to visit a site. (If however you would like to explore further, follow the instructions below).

First visit this site explaining traceroute

Next find a site that provides the common internet tools (traceroute, ping) some examples include http://centralops.net/co/ or http://network- tools.com/

Using the traceroute tool, answer the following questions:

Traceroute from the chosen site to curtin.edu.au - cut and paste the entire list of 'hops' from there to Curtin.

How many ‘hops’ are there?

what is the average time in milliseconds from the tools site to the curtin server?

For this task I started out using http://network- tools.com/
My first two attempts with this timed out after going through 11 routers or 'hops'. I got the timed out message after reaching the host gw1.er1.curtin.cpe.aarnet.net.au and this was on average after 123.5 ms (average of 247 ms round trip).

I then went looking for another traceroute site and used http://network.fasthit.net/ for my third attempt. Interestingly, it only took 5 'hops' to get to gw1.er1.curtin.cpe.aarnet.net.au instead of 11, and this traceroute tool actually got through to the curtin.edu.au host on the 6th 'hop'. The average time to reach a curtin.edu.au server was 1.234 ms. Now I'm wondering is this 'faster' time is real or is there a decimal point missing from the data output of my first two attempts? And if it really is faster - why? Is there such a thing as a better connected set of routers?

Chriso From Net11 says
Hanna the reson you get timed out is that the router you enconterd had a firewall to stop you from tracing the hops. nothing to do with theway you did it. as you can see that if you keep doing it the trace will take a different path each time. Hence the Word Internet
