When you set up your website, you’ll need to choose an address name for it. Its first goal is to help people visit your web page. This is also important for SEO (Search Engine Optimization) because search engines use it to rank.

In this article, we will explain what is a domain namehow it works, and how to choose the right one for your business!

Domain Name Explained

Simply put, it’s a website address on the internet. This is how people find pages when they type their name into a web browser.

A domain consists of a series of numbers called IP addresses. It helps to identify the location of the server where the website files are kept.

Some examples:

  • google site
  • facebook
  • Apple Network
  • Wikipedia
  • White House website

How do domains work?

When you type a web address into your browser, you’re telling your computer to visit the specific server that holds the website you’re looking for. A server is identified by a unique IP address consisting of a string of numbers.

However, humans can have difficulty remembering long strings of numbers. So DNS (Domain Name System) servers translate human-readable names into IP addresses.

When you type an address name into your browser, DNS looks up the associated IP address. It then directs your browser to the correct server. Once the browser is connected to the server, it can request and display the desired web page.

structure

The URL consists of three parts. They are subdomains, second level domains (SLDs) and top level domains (TLDs).

Subdomains

It is the first part of the name before the first dot. For example, in the example “blog.medicine.com”, “blog” is a subdomain.

It is usually used to build a new website on top of an existing website. Therefore, it is not required, and addresses can lack it.

SLD

SLD occurs between two points. For example, in the example “blog.medicine.com”, “medicine” is the SLD. SLD can be any combination of letters and numbers.

top level domain

The TLD is after the second point. In the example “blog.medicine.com”, “.com” is the TLD.

There are many different TLDs available, including .net, .org, and .info, but their number is limited. The most famous is .com.

What is the difference between a domain name and a URL?

Although people often tend to use the two terms interchangeably, they refer to two different things. The first is the unique identifier for the website. The second is a specific address for a specific page.

For example, the domain name for BBC News is “bbc.co.uk”. The URL of its home page is “https://www.bbc.co.uk/news”. A website can have dozens or even hundreds of different URLs, each corresponding to a different page.

How to register a domain name?

Names are assigned by ICANN (Internet Corporation for Assigned Names and Numbers). When you signed up for it, you leased from ICANN for a period of time.

The first step in registration is to choose a registrar. Once you have chosen it, you need to choose an appropriate name.

Once selected, you will need to pay the registration fee. Its cost depends on the registrar you use and the extension you choose. For example, .com TLDs are generally more expensive than .net TLDs.

You can renew your registration when it expires or let it expire. You can still extend your registration period for a certain period of time. It usually lasts 45-60 days. After the period ends, the name is back on the market and others can buy it.
