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.

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.

Be sure to choose a domain name or website address for your business that is easy to remember and if possible choose a name that relates to your business or service (i.e. tomsgarage.com). You can use this to your by registering multiple website addresses and having their website design optimize the web pages for all those key words. You can then point multiple website addresses at your website (i.e. sarahs-hair-studio.com, bestlocalhairstyles.com and quickperms.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.

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.
