Tracing route from CentralOps.net to curtin.edu.au [134.7.179.10]...

There are 19 ‘hops’ from CentralOps.net to curtin.edu.au.
The average time in milliseconds from the tools site to the curtin server is 246ms.

I pinged the webct site from my computer and compared the time with the time taken to ping from the net tools site.

Wictorias-iBook-G4:~ wictoria$ ping curtin.edu.au
PING curtin.edu.au (134.7.134.47): 56 data bytes
64 bytes from 134.7.134.47: icmp_seq=2 ttl=240 time=150.286 ms

It took about 150ms from my computer in Auckland compared to the 246ms from the CentralOps.net, which most probably is a computer in the US, hence the longer time it took to ping Australia.

There are 16 ‘hops’ from my computer in New Zealand to curtin.edu.au (compared to 19 from the CentralOps in the US).

Observation: The ping (round trip time) is dependent on the distance between the computers, but the number of hops (between routers or computers) seems less dependant on distance.
