Comment
Domain name root servers (identified by letters) are intermediaries between a computer and another server that match domain names to IP addresses. They form a dense and hierarchical global network with 13 root servers (of which 10 are in the United States) and their numerous instances (or copies) spread around the world. The map shows a high concentration in Europe and North America. After that come emerging countries and the Middle East, although the correlation between the number of servers and the share of Internet users is not verified everywhere.
