The internet is more of a physical than one might think. The Internet, at its core, is a collection of interconnected routers, and interconnected groups of routers called autonomous systems. These routers, and their interconnections are housed in only a buildings around the world. In this section we will dive into these locations.
The internet, and the relationships between networks and companies are managed by surprisingly few people - the network engineers and peering coordinators of the networks that make up the tier 1 and 2 networks (and sometimes tier 3).
Networks on The Internet are generally broken into 2 categories: Content creators / hosters, and content consumers. These are otherwise known, respectively, as Content Heavy networks, and Eyeball Networks.
Traceroute is a neat tool included in most operating systems. It works by sending packets with an increasing time-to-live or TTL, and recording the IP of each hop it recieves an ICMP response from. This allows it to build a list of hops on the path to a destination host or IP address.
