What is a Domain Name and Why Do You Need One?

By Kate J


Many of us wonder "What is a domain name?". They also question why it is necessary to have one. First off, it's very useful to understand what it actually is. A domain name is utilized to substitute numeric addresses with a name, which is quicker to remember. On the net, the IP (Internet Protocol) address is used to make contact with servers. The Ip is made up of four sets of three numbers. This is difficult for people to memorize. It's really a good deal simpler to associate that IP address using a domain name instead. For instance, the domain name google.com identifies a group of several IP addresses that could sometimes change. However, the visitor only has to remember google.com to reach that website.

It is helpful to know how domain names work when determining the answer to the question "What is a domain name?". There is an Internet protocol called DNS (Domain Name Service). Its job is to translate domain names into IP addresses. When the network equipment route data files all over the Internet, they use IP addresses to determine how to get a data packet from point A to point B. For example, an online browser will send a request to access the google.com website. The DNS service on your computer sends a request to obtain the IP address. After the IP address is received, the browser will connect with the server using that address. In the event the IP address is not recognized because the DNS services are down, it's close to impossible for the internet browser to make contact with the web page. That's the reason why a domain name is really important.

Someone that wants to open a web site needs a domain name. Not everybody memorizes IP addresses, and they are prone to change after some time. Luckily, it's very reasonably priced to purchase a domain name. The issue will likely be finding the one which has not yet already been taken by another individual. However, including several words and dashes are good methods to finding an unused domain name. The method to get a domain name for one's own website will not be challenging for anyone who knows the fundamentals of "What is a domain name?".

There are several good companies on the market where one can acquire a domain name at a very affordable price. The domain name for my web page www.websitefordummies.info cost me just $2.99/year. NameCheap is my personal favorite, but there are several other great companies to choose from. Go Daddy, and Bluehost are great website hosts which also offer domain names. Check out a handful of companies and select one that meets your requirements.

Those that can answer the question "What is a domain name?" will have a significantly easier time understanding how the world-wide-web functions and the way to manage a website. This is particularly useful when a website or desktop web browser is down. As an example, a knowledgeable user can identify very quickly if it is a DNS problem or not. That's the reason it will be beneficial to know how a domain name works.
