The Domain Name System or DNS is an international address system developed to ensure that every computer connected to the Internet has its own address. DNS assigns addresses to Internet web servers . However, in the DNS system, that address is actually a set of numbers like 220.127.116.11. This set of numbers is called the computer's Internet Protocol (IP) address.
The Domain Name System is most often described as the Internet’s phone book or address book. All of us Internet users use it on daily basis without even realizing it. Its basic task is to convert human-readable website name like coursera.org into its computer-readable numerical IP address like 18.104.22.168.Since such strings of numbers are difficult for humans to memorize, DNS allows you to assign a domain name, such as facebook.com to you IP address. So, the domain name is simply an address on the Internet. It has to be unique just like physical address or phone number.
Computers (and other network devices like smartphones or tablets) use IP addresses to identify each other on the network and route your request to the site you are trying to access. It is just like dialing a phone number to reach the person you want to talk to, but thanks to DNS, you don’t need to maintain your own address book of IP addresses. You will simply connect via DNS server (also called “domain name server” or just “name server”). Domain name system servers match domain names like coursera.org to their associated IP addresses.

A hierarchical system of servers and services specifically designed to translate IP addresses into domain names (forward lookups) as well as the reverse (reverse lookups) is called:
When you type in a web address, e.g.www.google.com. DNS associates with the domain name, translates into IP address (for example 192.168.154.70 is the IP for google.com) and directs your Internet connection to the correct website.
In order to first begin to create a website one needs not only come up with a name and logo, if they do not already have one, but also need to buy a domain name. The domain name can be bought from many different Host websites, such as GoDaddy and Network Solutions, and should be short and easy for people to remember and type. One is less likely to get traffic through their site if the domain name is hard to type and/or remember.
The IP address is given a unique identification it is one of kind IP address, so it can be trace for any internet activity and find the exact location of website. Domain names are used because it is easier to remember the name rather than the entire website address. All computers on the net have what area unit termed net Protocol addresses ordinarily called associate degree scientific discipline address to be ready to communicate across the network. These addresses, that area unit assigned to all or any computers on a network, area unit created of numerals separated by a dot that don't seem to be essentially simple for North American country to recollect. Therefore, whereas computers simply use these scientific discipline addresses to attach and communicate with one another, it's somewhat more difficult for North American country. It's with keeping such in mind that, net designers and controllers have return up with a translation system that identifies additional simply remembered characters with every and each scientific discipline address. With DNS we need to have the integrated namespace so following DNS use is proposed: an internal DNS namespace, used only on your own network; internal DNS to communicate with external DNS forwarding; and an external DNS namespace to communicate with external
DNS- DNS stands for domain name server and is a network of servers that keep track of Internet Domain Names. Its main job is to authenticate and find domains. It translates IP Addresses into numbers, for example, 22.214.171.124 translates into
When setting up a new website or business online, one of the most important steps in the process is the creation of a domain name. A domain name is the name that those on the Internet will use to find your website. It is contained in the URL for that particular page. It is a quick means to give users a glimpse into your site. The name you choose might be the name of your company or the services that you provide. It may include your location or any other information you wish to include. No matter what information you include, when a user encounters your domain name they should be able to tell who you are or what service you offer.
host name- A name made up of alphabetic, numeric, and some special characters, used to identify a specific IP host. Host names that follow the convention for domain names in the DNS system use a hierarchical design, with periods separating parts of the name.
The role of an IP address is to locate each device in the network. For example, having a Roku, Xbox One, two IPhone, a wireless printer, each device has its address. The domain name is a name given to companies, entities to communicate and share data through the network (e.g. intranet, internet, cloud).
It lets the server you are connecting to have a way to send information back to you. This address is unique to your device, and is even routinely updated and changed sometimes when you just reset your router. By using this type of identifier websites can ensure that the same computer that logged into the website before is doing so now, ensuring at the very least that someone in your household on your computer did so. A way to further ensure it was you starting this connection on your computer, the server may utilize HTTP authentication.
P1: The first method in network addressing is, Fully Qualified Domain Name which is known as FQDN for short. FQDN is used as the domain name for a specific host or computer name on the internet. FQDN consists of two main parts, the domain name and the hostname. For example, Belfast Met is the hostname, but the domain name is belfastmet.ac.uk.
