See which ISPs Google, Microsoft and Netflix trade Internet traffic with

The network interconnection deals between content providers and Internet service providers (ISPs) are often shrouded in secrecy, at least when it comes to the question of whether any money is changing hands. But it's possible to figure out which companies are directly exchanging traffic with ISPs by examining publicly available information if you know where to search.

Analyst Dan Rayburn shows which ISPs the likes of Google, Amazon, Facebook, Microsoft, Netflix, Pandora, eBay, and Apple have direct connections with. The connections are "public information that anyone can look up simply by knowing the networks' Autonomous System number (AS) and looking at their peers," Rayburn wrote. "You don’t have to be a networking engineer to look at BGP [Border Gateway Protocol] relationships and see what is taking place. It’s all public info."
