Okay, fair warning this is, as my friend Kanad would say, “Nerdy Gigabyting” stuff.
For all you Star Wars fans out there, and even some op engineers that may not like Star Wars check out these hops in your terminal shared with me my friend and co-worker Jason P.
#> traceroute 216.81.59.173
For those of you that are curious about what the hell a traceroute is, it is a way to see the set of network hops taken to get to the destination in question. For instance, when you visit http://www.seanshadmand.com from your computer the request is sent to your local network, then a nearby network and then the next switching and moving between networks until it arrived at the network that holds my website. Just ike taking multiple roads to get to and from work your request must travle through different “intersection” to get to a web page.
Here is an example of doing a traceroute to my DNS http://www.seanshadmand.com

Here you can see the request working its way from our local network to our Sonic.net provider all the way down to the network hosting my site, Amazon.
Okay, so here is what the original traceroute I mentioned above did in 64 hops – the following is a spoiler alert, do not scroll down if you want to try it yourself 🙂
