What is a Domain Name or a Website Name?
Your website communicates with other computers and the internet by using its network adapter or NIC (Network Interface Card) that is within the server. This card and thereby the server uses a unique address known as an IP address. An IPv4 ip address is a address annotated as four numbers segmented by dots. Each segment or octet can have a value between zero and 255, so your dedicated server or business computer address format would look similar to this: 172.16.65.17 On a Windows Server you can determine what the server ip address is by selecting the start button then selecting run. Type in ipconfig and click “OK”, a black command prompt should appear in which you can type ipconfig. On a Linux Server you can open a terminal window and type ifconfig. You can use the same command on your home Windows or Linux system to determine your static dedicated ip address.
Technology has simplified browsing for websites through the use of something called a host file. A host file translates a website name into the assigned IP address. So when you use your internet web browser to browse a website, it communicates to the web server using the ip address. The host file is stored in the c:windowssystem32driversetc directory on a windows computer and in the /etc directory on linux and unix systems.
Have you ever been to 1313 S Harbor Blvd in Anaheim California? Do you know what is at that address? If I had said “Have you ever been to Disney Land?” chances are that you would have immediately known what I was talking about. 131 S Harbor Blvd, Anaheim, California 92802 is the equivalent of an IP address, and Disney Land is the equivalent of a hostname. Website hosting is the equivalent of the land where Disney Land sits. So if you register a website address and get the name, you must also rent or purchase internet real estate or server space for your website to reside on. Likewise if you obtain website hosting but don’t register a website address, no one will know how to get to your website.
If you wanted your computer to look for www.npsis.com using the ip address 192.168.20.34, you would make an entry in your hostfile. The hostfile contains entries that look like this: 192.168.20.34 www.npsis.com. When you access the website www.npsis.com using your web browser, your computer would look for the ip address 192.168.65.14.
DNS (Domain Name System) is commonly used by Internet Service Providers to translate hostnames to IP addresses. When you type www.npsis.com or any other web address URL, your computer contacts a DNS server to find out what IP address is assigned to that domain name. All websites and servers have domain names if they are accessed over the internet.
It is important when selecting your website address that you pick a name that is easy to remember. The domain name should also reflect what your business does. For example the website address tomsgarage.com gives you a pretty good idea of what tom does for a living and its very easy to remember. You can also reserve multiple related domain names and point them at your website address as well. Have your website design store help you to incorporate several relevant key words into your website design and point all of your relevant website addressees at your website (i.e. wefixtires.com, bestlocaltireshop.com, toms-tires.com).
Domain names are typically done on a first come, first serve basis so if you have an idea for a good name you should register it before it is taken by someone else. There are many people and businesses who register and buy the most desirable domain names and resell them; this is usually for a higher cost than the original purchase price.
If you are dealing with a website design store or a web designer you will want to absolutely make sure that you own the domain name and not them. When you purchase a domain name yourself you better protect yourself from predators looking to take advantage of you.
