DNS (Domain Name System) is one of the basic building blocks of the internet. **One [domain name](https://www.nettescil.com.tr/alan-adi) (for example, [www.siteadi.com](http://www.siteadi.com)) IP The system that allows doğru to be redirected to the right server**. . DNS Thanks to operations, websites, email servers and other online services work smoothly.

## **1st DNS What and how it works?**

DNS (Alan Name System) on the internet **more easily rememberable domain names, numerical IP is a central system that translates to addresses**. .

???? **For example:**

- [www.google.com](http://www.google.com) → 142.250.74.14
- [www.yourwebsite.com](http://www.yourwebsite.com) → 192.168.1.1

DNSInternet users **IP using domain names instead of memorizing the addresses** allows you to access websites.

### **DNS Working Principle:**

1 1 **Write a domain name to the user browser** (for example, [www.siteadi.com](http://www.siteadi.com)).
2️⃣ **Browser, which is the name of this domain IP to determine the corresponding address DNS makes a query**. .
3 3 **DNS server, the corresponding domain name IP Return the address**. .
4️⃣ **Browser, this IP connects to the website via the address and the page is uploaded**. .

These processes occur in seconds.

???? **MX Registration (Mail Exchange Record):**
E-determines the mail server. For example:

- `mail.siteadi.com → mail sunucu IP`

???? **NS Registration (Name Server Record):**
Which domain name DNS Shows that it is connected to servers.
