Tracing from my PC

Tracing from my own computer to the Curtin server (in Perth? because technically, it could be anywhere in the world), I can see 192.168.2.1 which is my wireless router, but everything else is way over my head..

C:\Users\Nagamori>tracert 134.7.179.53

Funnily enough, the first few pings to Central Ops were 471ms and to Curtin it was 724ms and I was thinking that the Curtin server is in Australia, so it should definitely be faster from here(Sydney) to Perth, than it is from Sydney to Texas.

After a few pings, a faster route is found and Curtin settles to 73ms and Central Ops to 233ms.
