system database program used root Root Trust Anchor The Root Trust Anchor, or Key Signing Key, is used by DNSSEC-enabled software to verify the contents of the DNS root zone is valid. It additionally enables a single chain of trust to DNSSEC-enabled top-level domains and beyond.
Top-Level Domains A plain-text list of top-level domains, the delegated children in the root zone, are provided for sofware applications that need to be aware of current top-level domains. Root Files Root Hints
Operators who manage a DNS recursive resolver typically need to configure a "root hints file". This file contains the names and IP addresses of the authoritative name servers for the root zone, so the software can bootstrap the DNS resolution process. For many pieces of software, this list comes built into the software.

The complete root zone is available for download at the following locations. Ordinarily there should be no need to download this file on a regular basis, as the contents of the file are served via the DNS system itself.

This file holds the information on root name servers needed to initialize cache of Internet domain name servers(e.g. reference this file in the "cache . "configuration file of BIND domain name servers).
