E.root-servers.net

March 28, 2021

NASA operates E.root-servers.net, one of the thirteen logical Internet Root name servers. NASA cooperates with the eleven other Root Server Operators to provide authoritative data for the DNS Root Zone. The E-Root Server system is operated by the Information Technology Operations Division at NASA Ames Research Center under the direction of the Ames Office of the Chief Information Officer.

E-Root receives DNS queries over IPv4 at 192.203.230.10 and over IPv6 at 2001:500:A8::E.

The Domain Name System is a distributed hierarchical database of resource records that permit (among other things) the translation of hostnames into IP addresses and vice versa. The root of this hierarchy is anchored on 13 domain name servers scattered across the globe. E-Root uses IP Anycast to provide service from a number of locations throughout the world which may change from time to time.
