DNS Standard Set ka ek Protocol hai, Jo internet aur other private network par data ka exchange kaise hoga yeh tay karta hai jise TCP/IP Protocol Suit ke roop mein jana jata hai.
Kisi bhi website ka URL www.google.com Jaise hota hai, lekin asal mein iss URL ke peeche har ek domain name ko ek IP Address Assign hota hai.


Basically, iska kam kisi bhi user-friendly domain name jaise www.google.com ka Internet Protocol (IP) Address 74.125.200.103 hai aur ise Network par ek-dusre ki pehchan karne ke liye Computer Ke Zariye Use kiya jata hai.
Internet par Computer aur other Network Devices IP Address ka use karke aapke dwara di gayi request ko root karte hai, jisse woh website open ho sake.
Yeh thik vaisa hi hai jaise aap apne mobile se phone number dial kar call karte hai. Lekin DNS ki wajah se apko har ek Site ka IP Address yaad nahi rakhna hota hai.
Toh jab aap apne Browser mein uss Website ka name type kar enter karte hain, Toh aap Domain Name Server jise DNS bhi kaha jata hai se connect hote hain jo ek bahut bade Database ko Manage karta hai, jisme har ek domain name ko uske IP Address se Map kiya jata hai.
DNS Server se Related IP Address se Domain name ko Match karta hai. Jab aap apne Browser mein ek Domain Name type karte hain, To apka Computer apne present DNS Server se contact karta hai aur puchhta hai ki IP Address Domain Name se connect hota hai aur apke liye sahi Webpage ko open karta hai.

Domain Names Website ke aise Address hote hain, jise hum yaad rakh sakte hain aur har din use karte hain. Jaise ki Google ka Domain Name google.com hai aur apko Google par jana hota hai, tab aap apne Web Browser ke Address Bar mein google.com enter karte hain.


Lekin, aapka Computer nahi samajhta ki "googal.com" kanha hai. Kyonki Internet aur other sabhi Network  Numerical IP Address ka use karte hain, Jaise ki 172.217.0.142 yeh IP Address google.com ke liye hain.
Yadi aap yeh number apne Web Browser ke Address Bar mein type karte hain, To aap Google ki Website par ja sakte hain.
Lekin hum 172.217.0.142 ke bajaye google.com ka use karte hain kyonki google.com jaise Address ko hum aasani se yaad rakh sakte hain.

How Does DNS Work, DNS Kaise Kam Karta Hai?

Jab bhi koi Internet usee kisi Domain jaise status brother.com par jata hai, to apka Computer ya Smart Device kayi Steps ko Follow karta hai jo Human-Readable Web Address ko Machine-Readable IP Address mein Change kar deta hai.
Chahe aap Website ko Access kar rahe ho ya E-mail bhej rahe ho, apka Computer apke dwara use kiye jane wale Domain Name ko dekhne ke liye ek DNS Server ka use karta hai. Iss Process ko DNS Name Resolution Keh sakte hain.
How to Work DNS

The Steps Of DNS:

Aap Windows ya Apple OS (Operating System) ke Browser mein google.com Domain Name type karte hain.
Client ko iske IP Address ka pata hona chahiye ki google.com Earth par kanha par located hain. (Generally Sabhi Website Internet Data Center Mein Host Kiye Jate Hain)
Apka Browser PC ke Operating System ko yeh Query bhej dega.
Pratyek Operating System kuch DNS Server ko Query karne ke liye Configure kiya gaya hai. Generally apke ISP ya Network Administrator aise DNS Server ko Configure karte hain, jise Resolving Name Server kehte hain.
Iss Name Server Ko Resolve karne wale ko google.com ke Location ke baare mein jankari nahi hoti, Lekin woh yeh janta hai ki Root Server kanha par hain.
Aage, Resolving Name Server TLD(Top-Level-Domain) Name Server ke Location ko Search karta hai aur google.com ke liye Query bhejta hai. Internet par pratyek Domain ko ek adhikarik Name Server hota hai.
Last mein, yeh adhikarik Name Server apko google.com ka Accurate IP Address dega. Yeh Information Resolving Name Server par wapas aa jayegi, jo iss Information ko Cash karya hai aur Owner ko Browser ke pas bhejta hai.
Aakhir mein aap Google Search ka home page dekh sakte hain.

Some More Details On DNS Server:

Zyadatar case mein, Do DNS Server, Ek primary aur ek secondary Server hota hai. Yeh ya to apke Router aur ya apke Computer par apke ISP se DHCP dwara Connect karte samay Automatic Configure hote hain.
Aap do DNS Server ko Configure kar sakte hain, Inmein se ek Fail hone par dusre Server ka use kiya jayj hai.
Kuch DNS Server ka dusro ke comparison mein Fast Access Time Hota hai, lekin yeh poori tarah se depend karta hai ki DNS Server tak Access ke liye apke Devices par kitna time lagta hai.
Apko Network se Related Problems ko Face karna pad raha hai, Janha aisa lagta hai ki koi Website load nahi ho tahi hai, to sambhav hai ki DNS Server se koi Problem ho.
