A root name server is a name server for the Domain Name System’s root zone. It directly answers requests for records in the root zone and answers other requests returning a list of the designated authoritative name servers for the appropriate top-level domain (TLD). The root name servers are a critical part of the Internet because they are the first step in translating (resolving) human readable host names into IP addresses that are used in communication between Internet hosts.

Q: Does all Internet traffic pass through the root name servers?
A: No Internet traffic passes through the root name servers at all. They have nothing to do with routing, note the difference in spelling. Name servers just answer queries from other parts of the DNS.
