Researchers Map Locations of 4,669 Servers In Netflix's Content Delivery Network

Wave723 writes from a report via IEEE Spectrum: For the first time, a team of researchers has mapped the entire content delivery network that brings Netflix to the world, including the number and location of every server that the company uses to distribute its films. They also independently analyzed traffic volumes handled by each of those servers. Their work allows experts to compare Netflix's distribution approach to those of other content-rich companies such as Google, Akamai and Limelight. To do this, IEEE Spectrum reports that the group reverse-engineered Netflix's domain name system for the company's servers, and then created a crawler that used publicly available information to find every possible server name within its network through the common address nflxvideo.net. In doing so, they were able to determine the total number of servers the company uses, where those servers are located, and whether the servers were housed within internet exchange points or with internet service providers, revealing stark differences in Netflix's strategy between countries. One of their most interesting findings was that two Netflix servers appear to be deployed within Verizon's U.S. network, which one researcher speculates could indicate that the companies are pursuing an early pilot or trial.
