À la demande de l'agence américaine pour les projets de recherche avancée de défense (DARPA), Jon Postel et Paul Mockapetris conçoivent le DNS et en rédigent la première implémentation en 1983.
The DNSCrypt protocol, which was created in 2011 exterior the IETF requirements framework, released DNS encryption around the downstream facet of recursive resolvers, wherein purchasers encrypt query payloads applying servers' general public keys, which are released while in the DNS (instead of relying on 3rd-celebration certificate authorities) and which can subsequently be safeguarded by DNSSEC signatures.[fifty] DNSCrypt utilizes either TCP or UDP port 443, precisely the same port as HTTPS encrypted web targeted traffic. This released not merely privateness regarding the articles on the query, but also a big measure of firewall-traversal functionality. In 2019, DNSCrypt was further more extended to help an "anonymized" method, just like the proposed "Oblivious DNS", during which an ingress node receives a query that has been encrypted with the general public critical of a different server, and relays it to that server, which acts being an egress node, accomplishing more info the recursive resolution.
SRV record qui généralise la Idea de MX record, mais qui suggest aussi des fonctionnalités avancées comme le taux de répartition de demand pour un assistance donné, standardisé dans la RFC 2782[27] ;
Dabei werden einem anfragenden shopper zusätzlich zu der korrekten Antwort, manipulierte Daten übermittelt, die dieser in seinen Cache übernimmt und später, möglicherweise ungeprüft, verwendet.
[53] DNSCurve is proposed instead to DNSSEC. Other extensions, like TSIG, include guidance for cryptographic authentication in between trusted friends and are generally used to authorize zone transfer or dynamic update functions.

The DNS demonstrates the construction of administrative duty on the Internet.[5] Each individual subdomain can be a zone of administrative autonomy delegated to the supervisor.
Une des failles mises en avant est la possibilité d'intercepter les paquets transmis. Les serveurs DNS communiquent au moyen de paquets uniques et non signés. Ces deux spécificités rendent l'interception très aisée.

To provide resilience from the event of computer or community failure, several DNS servers tend to be delivered for coverage of each domain. At the very best amount of worldwide DNS, thirteen groups of root name servers exist, with added "copies" of these dispersed all over the world by means of anycast addressing.
