What a Domain Name ( is and How they Work ?

What a domain name?

A domain name helps us reach an IP address. A domain name helps you to reach a website without knowing the IP address.

How many kinds of domain names are there? The main top level domain names are .com for companies, .net fot network , .org for organizations .edu for schools or colleges & .gov for government websites.

In India you will also find domain names ending in .com,, .in as well. It is important that you choose a good domain name for your website.

Choose a domain name that is short easy to remember Which has some originality is easy to spell.

How to Work ?

Domain names were created to make IP, or Internet Protocol, addresses more human-friendly. An IP address is a unique set of numbers that is assigned to every computer on the Internet.

Think of IP addresses like street addresses — they identify where a computer is located on the Internet and help route information so that it can easily travel between computers. But IP addresses, like this one, don’t exactly roll of your tongue, do they? And then just imagine having to memorize such a string of seemingly random numbers for every single website you wanted to find on the Internet.

If only there was an easier way — actually, there is. While computers require IP addresses to locate one another, we humans can use domain names.

The Domain Name System, or DNS, takes domain names, the kind of web addresses that people understand like and translates them into IP addresses that computers need to communicate.

So instead of having to remember, you can simply remember Much easier, right?

When visitors enter your domain name into a Web browser, the browser uses your Domain Name to find the correct IP address and, in turn, passes back the website associated with that IP address.

Think of this way; your domain name functions like the contacts you store in your mobile phone.

When you touch the name of a contact that’s stored in your mobile phone, your mobile phone automatically dials the number you’ve saved for that contact.

You don’t need to know where the person you’re calling is located, and you don’t need to even enter their specific phone number.

All you do is touch the contact and mobile phone does the rest.

Remember, domain names provide you with a simple, human-friendly way to locate websites on the Internet.

DNS Server Works ?

In the world of networking, humans identify names instead of numbers. So to bridge the communication gap between computers and humans and make communication a lot easier, networking engineers developed DNS, and DNS stands for a domain name system. And DNS resolves names for numbers, to be more specific it resolves domain names to IP addresses.

So if you type in a web address in your web browser, DNS will resolve the name number because only the computer knows the number. So for example if you want to visit a certain website, you will open your webbrowser and type in the domain name of that website, so for example let’s use

Now technically you don’t really need to type Yahoo web page. You can type in an IP address instead, if you already know what an IP address is, but since we are not tomorrowsing and dealing with numbers, especially when there are millions of websites on the Internet. , Then we can type in the domain name instead and let DNS convert it to an IP address for us.

For Example

So for our example,

when you type the DNS server in your web browser through its database to find a mail IP address for your domain name, and when it searches, it shows that domain.

The web site will resolve the name to Yahoo’s IP address, and once which is then done, your computer is able to communicate with the Yahoo webserver and retrieve the webpage.

So DNS basically works like a phone book, when you want to find a number, you don’t look at the number first, you look at the name, then it will give you the number. So check the steps taken by DNS to take it further. So when you type in in your web browser and if your web browser or operating system cannot find the IP address in its cache memory, it will send the query to the next level called the resolver server.

The resolver server is basically your ISP or Internet service provider, so when the resolver receives the query, it will check its cache memory to find an IP address for, and if it doesn’t cancel it This will send the query to the next one. The level that is the root server. The root server header or root off is a DNS hierarchy.

There are 13 sets of these root servers and they arestrategically deployed worldwide, and they are operated by 12 variants and each set of these root servers has its own unique IP address.

When the root server receives a query for the IP address, the root server does not know what the IP address is, but the root server knows where to send the resolver to help find the IP address. The resolver from the root server will be directed to the TLD or top level. For domain com .com domain.

TLD server

So the resolver will now ask the TLD server for for the IP address. Top level domain servers store there address information for top level domains, such as .com, .net, .org and and so. This particular TLD server manages the dotcom domain in addition to

So when a TLD server receives an IP address query for, the TLD server is not going to know the IP address for

The TLD will then direct the resolver to the current and final levels, which are the official name servers. So once again the resolver will ask the official name server for the IP address of

The official name server or server is responsible for knowing everything about the domain that includes IP address. They are the last authority.

So when the query server does the official name resolver, the name server will respond with IP address for And finally the resolver will tell your computer the IP address for and then your computer can now retrieve the yahoo webpage.

It is important to note that once the thesaurus acquires an IP address, it will store it in its cache memory in case of another query for so that it does not have to go through all the these steps again.

Domain Name Renewal
