What is a domain name? — explained for absolute beginners


If you’re new to the internet or thinking about starting a website, you might have heard the term “domain name” and wondered what it actually means. Don’t worry — you’re not alone! This guide explains domain names in plain, easy-to-understand language.


What is a Domain Name?

Think of the internet like a giant city. A domain name is simply the street address you type into a map to get to a specific house or shop.

In technical terms:

  • Domain name = the address
    Examples: example.com or myshop.co.uk. When you type this into your browser, it tells the internet which website you want to visit.
  • It’s not the website itself
    The domain name points to the computer (server) where the website lives. The website’s pictures, text, and videos are stored on that server.
  • Unique and registered
    Only one person or business can own a specific domain at a time. You get one by registering it with a domain registrar, usually for a small yearly fee.

A Simple Analogy: Mailing vs Browsing

Think of it like postal mail:

  • Postal mail: Your name + street address → the mail carrier delivers to the right house.
  • Internet: Your browser + domain name → the internet routes you to the correct server.

Parts of a Domain Name

Every domain name has a few key parts:

  1. Subdomain (optional): www — like a room inside the house.
  2. Main name: example — the name you choose.
  3. Top-level domain (TLD): .com, .co.uk, .org — like the neighbourhood or country code.

So www.example.com breaks down into:

  • Subdomain: www
  • Name: example
  • TLD: .com

How Domain Names Work (Very Simply)

  1. You type a domain into your browser.
  2. A system called DNS (Domain Name System) looks up which server IP address matches that domain.
  3. Your browser connects to that server and displays the website.

Tips for Choosing a Domain Name

  • Keep it short, easy to spell, and memorable.
  • Pick the right TLD (e.g. .co.uk if your business is UK-focused).
  • Buy from a reputable registrar and enable auto-renewal to avoid losing it.
  • Consider domain privacy to keep your contact details hidden from the public.

Final Thoughts

A domain name is your website’s online address — simple, but extremely important. Choosing the right domain can make your website easier to find, more memorable, and more trustworthy to visitors.
