The computer is a machine and understands machine language only. IP addresses are used by computers to find a website on the internet. Actually, IP addresses are a combination of complex numbers and alphabets which the only computer can memorize.
For human ease, IP addresses are replaced by domain names to reach sites on the internet. Let’s delve into the must-have information about domains.
In the start, we have discovered why the domain name is used. Now we will move on to know what they are and how they work.
A combination of letters or numbers used in conjunction with domain extensions such as .com, .net, .org, etc is known as domain names. Let’s have a look at “www.noaccountcasino.com”, in this, ‘noaccountcasino’ is a domain name with .com as a domain extension.
As stated earlier domain names are addresses. Let’s look at examples from daily life, say that your home is a website than an address to your home would be the domain name.
If you have planned to go online then you are required to make a website of your own. And you can have a website only if you have a registered domain name. Every website on the internet has its own unique domain name. Two or any number of websites cannot have the same domain name.
You know that building a site isn’t enough in getting your business online. You also have to choose a website host to make a good name out there.
Why Do I Need a Domain Name?
See, even in your society if anyone needs to meet you he will be required to have an address. Likewise, if you have brought your business on the internet here, it plays a crucial role in selling your services.
If you have a domain name then it means that your copyright and trademark are safe. The domain name will ensure that you are on the way to building your credibility and you will find it helpful in enhancing your business like never before.
The online presence of your business is subjected to the domain name.
What Is Domain Name System (DNS)?
As we have discovered that domain name is user-friendly instead of a commonly used computer-friendly IP address to reach a website. But how the computer understands the domain name as it only uses IP addresses. This is where the concept of the Domain Name System(DNS) needs to be known.
DNS is more like a telephone directory for the internet. It fetches the domain names, translates them into IP addresses, and sends them to the browser to load the asked website.
So more specifically DNS is an interpreter that works between user and computer to facilitate the user.
How does DNS Work?
DNS works as an interpreter but it has a complex system of servers that are included in all the process of translating domain names and loading required webpages. Before going to the servers we will try to understand the general working system of DNS.
Here we start!
When a user enters a certain domain name to access DNS starts to translate these user-friendly domain names into machine-friendly IP addresses to locate the webpage.
The 4 servers included in this process are as follows:
DNS Recursor: It is the first server in the translation process that asks other DNS servers to check domain names if they have.
Root Name Server: It answers the request for records in the root zone and answers other requests.
TLD Nameserver: Top Level Domain or TLD name server is concerned with the rightmost part of the domain in translating it into an IP address.
Authoritative Name Server: It is the server that gives the IP address against our asked domain name.
So far we have undergone the domain name, DNS, and its working system but still concepts regarding domains need to be understood.
What are Subdomains?
Subdomains are part of the main domains. Well, do we need subdomains?
Yes, if you are having a complex website then you need a subdomain to facilitate the user to easily navigate through your website. Subdomains serve the purpose of organizing your website.
Subdomains can be any type of text but remember they must be easy to remember, understand, and memorize as well. If you want to have a subdomain then it must serve your purpose and should be catchy.
How to choose a domain name?
If you end up choosing the right domain name for your website it means you have taken a step towards online success. But how to choose?
Many names spin our minds when we are to make a decision. There are many things you have to consider.
First of all make sure that you choose a domain name that reflects your business, brand, or idea which you are planning to make live. It will be easy for users to find you if you do so.
If the username for which you are looking is already taken by someone then you have to come up with an alternate name but it must correspond to your website. You can also use suggested names given by the registrar.
Now is a good time to get your business online. All you need to know is that first of all you have to come up with a good domain name. The key to a good domain name is that it should be catchy and easy and it must correspond to your website.
