A domain name is a unique internet address that identifies a website on the internet. Users enter domain names into their web browsers to access specific websites. Instead of using a complex IP address (e.g., 192.168.1.1), a domain name allows for easy recall and navigation to a website.

How Does a Domain Name Work?
When a user types a domain name into a browser, the following steps occur:

1. Domain Name to IP Address Translation – The request is sent to a DNS (Domain Name System) server, which converts the domain name into the corresponding IP address.
2. Connection to the Web Server – The browser connects to the server hosting the domain.
3. Website Display – The server sends the website content back to the user.

Structure of a Domain Name
Every domain name consists of several parts:

• Subdomain – An optional prefix before the main domain (e.g., blog.mydomain.com).
• Second-Level Domain (SLD) – The main part of the domain that you register (e.g., mydomain).
• Top-Level Domain (TLD) – The domain extension that defines the type or region of the website (e.g., .com, .org, .net, .cz).

Types of Domain Names

1. Generic Top-Level Domains (gTLDs)
   • International domains such as .com, .org, .net, .info.
   • Suitable for global businesses and projects.
2. Country Code Top-Level Domains (ccTLDs)
   • Country-specific domains like .cz (Czech Republic), .de (Germany), .uk (United Kingdom).
   • Ideal for local businesses.
3. New Generic Top-Level Domains (ngTLDs)
   • Custom extensions like .shop, .blog, .tech, .app.
   • Useful for niche websites and startups.

How to Choose the Right Domain Name?

• Keep it Simple and Memorable – Short and clear domain names are easier for users to remember.
• Make it Relevant to Your Website’s Content – The domain should reflect your brand or business purpose.
• Use Keywords for SEO – Optimizing your domain for search engines can improve visibility.
• Avoid Special Characters and Numbers – These can confuse users when typing the domain.
• Select the Right Extension (TLD) – Use .com for international sites, .cz for Czech businesses.

1. Choose a Domain Registrar
2. Check Domain Availability – Use a registrar’s search tool to find available domains.
3. Register the Domain – Fill out the registration details and pay the annual fee.
4. Configure DNS Records – Link the domain to your web hosting.
