What Is a Domain Name?
A domain name is the human-readable address of a website. Instead of remembering numerical IP addresses like 192.168.1.1, users can simply type a domain such as example.com.
A domain typically has two main parts:
- Name: example
- Extension (TLD): .com, .in, .org, etc.
Together, they form a complete website address.
How Does a Domain Work?
Behind the scenes, domains work through a system called DNS (Domain Name System).
Here’s a simplified flow:
- You type a domain name in your browser
- DNS finds the matching IP address
- The browser connects to the server
- The website loads on your screen
Think of DNS as the internet’s phonebook.
Domain Name Example Explained
Let’s break down blog.example.co.in:
- .in → Country code (India)
- .co → Commercial category
- example → Brand or website name
- blog → Subdomain
Each part has a specific purpose.
