DNS, DNS सर्वर की मदद से काम करता है। जब कोई व्यक्ति वेब ब्राउज़र में डोमेन कॉल में प्रवेश करता है, तो अनुरोध DNS सर्वर पर जा रहा है।

DNS सर्वर एक लुक-अप तालिका का उपयोग करके IP सौदे को निर्धारित करता है। फिर यह उचित सर्वर के माध्यम से उपयोगकर्ता के इंटरनेट ब्राउज़र को पूछे गए तथ्यों को भेजता है।
इसके अलावा, एक DNS मशीन का अपना निजी समुदाय होता है। यदि एक डीएनएस सर्वर नहीं जानता है कि किसी विशेष डोमेन कॉल का अनुवाद कैसे किया जाए,

तो वह दूसरे सर्वर से, फिर किसी अन्य सर्वर से, और आगे भी, जब तक कि उन्हें एक उपयुक्त आईपी पता नहीं मिल जाता है, पूछेगा।

एक DNS सर्वर अपने डोमेन नामों के संयोजन में सभी आईपी पतों की एक सूची रखता है,

जिसे आवश्यकता पड़ने पर पुनः प्राप्त किया जा सकता है।

How does DNS increase  performance?


Servers can cache the A records, or IP addresses, they receive from DNS queries for a set amount of time. Caching promotes efficiency, enabling servers to respond quickly the next time a request for the same IP address comes in.
For example,

if everyone in an office needs to access the same training video on a particular website on the same day,

the local DNS server would only have to resolve the name once, and then it can serve all the other requests out of its cache.

The length of time the record is held — also known as the time to live (TTL) — is set by administrators and depends on various factors.

Longer time periods decrease the load on servers, and shorter ones ensure the most accurate responses.
DNS caching


The goal of DNS caching is to reduce the time it takes to get an answer to a DNS query. Caching enables DNS to store previous answers

to queries closer to clients and get that same information to them faster the next time it is queried.
DNS data can be cached in a number of places. Some common ones include the following:


Browser.

 Most browsers, like Apple Safari, Google Chrome and Mozilla Firefox, cache DNS data by default for a set amount of time.

The browser is the first cache that gets checked when a DNS request gets made, before the request leaves the machine for a local DNS resolver server.
Operating system (OS).

 Many OSes have built-in DNS resolvers called stub resolvers that cache DNS data and handle queries before they are sent to an external server. The OS is usually queried after the browser

or other querying application.


Recursive resolver. 

The answer to a DNS query can also be cached on the DNS recursive resolver.

Resolvers may have some of the records necessary to return a response and be able to skip some steps in the DNS resolution process.

For example, if the resolver has A records but not NS records, the resolver can skip the root server and query the TLD server directly.
