!!! Overview
[{$pagename}] ([DNS]) is a [hierarchical] [decentralized|Decentralized system] [Discovery Mechanism] or [Name Service] for [Devices], [services], or other [resources] connected to the [Internet] or a private [network].

Most prominently, it translates more readily memorized domain names to the [numerical IP addresses|IP Address] needed for locating and identifying computer services and devices with the underlying network [protocols]. By providing a worldwide, distributed [Directory Service], the [{$pagename}] is an essential component of the functionality on the [Internet], that has been in use since [1985|Year 1985].

!! [{$pagename}] [Privacy Considerations]
[DNS Privacy Considerations] ([RFC 7626]) describes the privacy issues associated with the use of the [{$pagename}] by [Internet] users. 

!! [Security Considerations]
Unencrypted [DNS] queries may be intercepted or manipulated without [End-User]'s knowledge. An [eavesdropper]—e.g., the owner of a [Wi-Fi] [router] or party in the [ISP] infrastructure—can see where users seek to browse, even if the content delivered from the [website] [data] is encrypted. [DNS] queries can also be [hijacked|hijack] to divert a user to a [Malicious Endpoint] ([website]) instead of the intended [website]. 

In [2019|Year 2019], the [United States Department of Homeland Security] ([DHS]) issued its first emergency directive to [United States Federal Agencies|United States Federal Agency] in response to a [DNS] [hijacking|Hijack] campaign.
