What is a Domain Name or a Website Name?
Most network adapters within servers and computers are assigned a unique address known as an IP address. An IPv4 ip address is a address written as four numbers separated by periods. Each number can have a value between zero and 255, so your dedicated server or home computer address format would look somewhat like this 172.16.3.44. You can find out what your ip address is by typing ipconfig at the command prompt (Start, Run, ipconfig) on a Windows Server and by typing ifconfig on a Linux Server. You can use the same command on your home Windows or Linux system to determine your static dedicated ip.
When you browse for websites on the internet your browser communicates with web servers via their IP address. Methods have been devised to assign human readable names or hostnames to ip addresses. On a local windows or linux computer this translation can be accommodated in what’s called a host file. On most windows systems the hosts file is located in c:\windows\system32\drivers\etc\ directory; on Linux or Unix servers the hosts file is commonly stored in the /etc directory.
Have you ever been to 3111 World Dr. in Orlando Florida? Do you know where that is? You may be able to figure out what location I am talking about but wouldn’t it be easier if I said have you ever been to Disney Magic Kingdom? That is essentially name resolution 3111 World Dr. Orlando, Florida 32830 is equivalent to the IP address and Disney Magic Kingdom is equivalent to a hostname. The server space or website hosting is equivalent to the land that the theme park sits on. So when you register for a domain name you get the name but you also must rent or purchase some “land” or server space for your website to reside. Likewise if you rent or buy the server space but do not register a domain name or an address, no one will know how to get to your website.
A hostfile will contain lines that look like this: 192.168.20.34 www.npsis.com which basically says that the ip address 192.168.20.34 corresponds to the hosname or webserver www.npsis.com. Hostfiles are used for name translation for a small number of computers.
For hostname to IP translation on the internet the DNS (Domain Name System) is commonly used. When you type www.npsis.com or the name of your website design store or the website name of your company, your computer contacts a DNS server to find out what IP address goes with the domain name or URL that you entered. Whether you are setting up website on a webserver or an email server you need a domain name.
If you are selecting a domain name or website name for your business it is to your advantage to select a domain name that is easy to remember and if possible reflects what your business or service is (ex. tomsgarage.com). You can also register multiple domain names and have your website design store optimize your web pages for those keywords. Then you can have multiple domain names point to your web site. So you could have tomsgarage.com, bestlocalgarage.com, and wefixcars.com all point to your website.
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.
Have you hired a web design store or individual web design consultant? Make absolutely sure that you own your website address and not them. By purchasing your domain name yourself, you protect yourself from negligent people and predators looking to take advantage of the fact that you might not know better.
