Open Root Server Network (ORSN) was a network of Domain Name System root nameservers for the Internet. ORSN root zone information was normally kept in synchronization with the "official" root nameservers coordinated by ICANN.
The DNS root zone is the top-level DNS zone in the hierarchical namespace of the Domain Name System (DNS) of the Internet.. Before October 1, 2016, the root zone had been overseen by the Internet Corporation for Assigned Names and Numbers (ICANN) which delegates the management to a subsidiary acting as the Internet Assigned Numbers Authority (IANA).

A list of the top-level domains by the Internet Assigned Numbers Authority (IANA) is maintained at the Root Zone Database. [1] IANA also oversees the approval process for new proposed top-level domains for ICANN. As of April 2021, their root domain contains 1502 top-level domains.
A root name server is a name server for the root zone of the Domain Name System (DNS) of the Internet. It directly answers requests for records in the root zone and answers other requests by returning a list of the authoritative name servers for the appropriate top-level domain (TLD).
Open Root Server Network logo. Open Root Server Network (ORSN) was a network of Domain Name System root nameservers for the Internet. ORSN DNS root zone information was kept in synchronization with the "official" Domain Name System root nameservers coordinated by ICANN. The networks were 100% compatible, though ORSN was operated independently.
This task involves liaising with top-level domain "Registrar-of-Record"s, the root nameserver operators, and ICANN's policy making apparatus. [12] Since the root zone was cryptographically signed in 2010, IANA is also responsible for vital parts of the key management for the DNSSEC operations (specifically, it is the "Root Zone KSK Operator
The root servers form the top of the hierarchical Domain Name System that supports most modern Internet communication. Verisign also generates the globally recognized root zone file and is also responsible for processing changes to that file once they are ordered by ICANN via IANA and approved by the U.S. Department of Commerce. Changes to the ...
