The DNS is made up of many servers and databases which, through a series of lookups in various caches, configure [[Domain Name]]s into [[IP Address]]es. The Domain Name System is a distributed database arranged hierarchically; its purpose is to provide a layer of abstraction between Internet services (web, email, etc.) and the numeric addresses (IP addresses) used to uniquely identify any given machine on the Internet. The DNS associates a variety of information with the domain names assigned and, most importantly, translates the domain names meaningful to humans into the numerical identifiers that locate the desired destination.

==Developments and the "DNS Camel"==
In 2012, an [[IETF]] draft proposal, called "DNS Extension for Autonomous Internet (AIP)," was written by three Chinese technologists suggesting a method of operating alternate DNS root servers within national boundaries using gateways for translation. All DNS requests would carry an additional TLD, in order to designate that the requests were being sent to an alternate root.

All DNS requests would carry an additional TLD, in order to designate that the requests were being sent to an alternate root. The standard would add a single letter to the DNS string - for example, "yahoo.com.B" - to designate the address of the alternate, nationally-controlled root.<ref name="ietfaip">[https://datatracker.ietf.org/doc/draft-diao-aip-dns/ IETF Data Tracker - Internet Draft: DNS Extension for Autonomous Internet], expired April 19, 2018</ref>
At the time, critics noted that the proposal would allow greater governmental control over the Internet.<ref>[http://domainincite.com/9474-china-proposes-to-split-up-the-dns China proposes to split up the DNS, domainincite.com]</ref> The Internet Draft expired in April 2018 after eleven proposed revisions.<ref name="ietfaip" /> The draft was one of many efforts to create [[Alternative Roots|alternative root systems]] for the Internet.

The [[DNS Camel]] refers to the overloading of features and protocols onto the DNS architecture, such that one small addition will "break the camel's back."
