Web hosting is a service that allows individuals or organizations to store their website files (HTML, CSS, images, databases, etc.) on a server that is connected to the internet. When someone types your website’s address (like www.example.com) into a browser, the hosting server delivers the content to them.
In simple terms:
🏠 Web Hosting is the “house” where your website lives.
🌍 Domain Name is the “address” to find that house.

🌍 What Is a Domain Name Server (DNS)?
A Domain Name Server (DNS) is like the phonebook of the internet. When you enter a website URL like www.google.com, DNS translates it into the actual IP address of the web server (like 142.250.190.14) so your browser can load the site.
How DNS Works:
-
You type
www.example.com. -
The DNS checks which IP address is linked to that domain.
-
It sends your request to the correct hosting server.
-
You see the website on your screen.
🔗 Key DNS Records
| DNS Record | Purpose |
|---|---|
| A Record | Maps domain to IPv4 address. |
| AAAA Record | Maps domain to IPv6 address. |
| CNAME | Aliases one domain to another (e.g., www to example.com). |
| MX Record | Defines email servers for your domain. |
| TXT Record | Used for SPF, DKIM, and domain verification. |
| NS Record | Points to name servers responsible for your domain. |
