Domain name systems (DNS) are essential for the functioning of the internet. Each DNS domain is managed by a different type of device.

The Domain Name System Security Extensions (DNSSEC) are a set of extensions to the Domain Name System (DNS) protocol to provide cryptographic security for DNS data. DNSSEC was developed in response to concerns about DNS security and integrity.

The DNS root is a device located in the United States Department of Defense (DoD) that is responsible for the authoritative name server for the .mil top-level domain.

The root zone is updated approximately every two weeks.

A device that operates as a DNS server is responsible for resolving domain names to IP addresses. DNS servers are found on the public internet, as well as on private networks.
