Most NICs or Network Interface Cards within servers and computers are assigned a unique address known as Internet Protocol or IP address. An IPv4 ip address is a 32-bit numeric address written as four numbers separated by periods. Each number can be zero to 255. An ip address for a dedicated server using NAT (Network Address Translation) or your business computer would look similar to this 192.168.20.34 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 type this command on your home Windows or Linux or Unix computer as well to find 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:\windows\system32\drivers\etc\ directory on a windows computer and in the /etc directory on linux and unix systems.

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.

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).

Website domain names are reserved on a first come, first serve basis. So if you have an idea for the perfect website address, you should reserve it before you’re your good idea is taken by somebody else. There are many companies and individuals who potentially popular domain names and resell them for a profit.

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.
