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:\windows\system32\drivers\etc\ directory on a windows computer and in the /etc directory on linux and unix systems.

If I asked “Have you ever been to Disney World?” more than likely you would associate Disney World with the theme park in Florida and you would know would quickly be able to respond either yes or no. But if I said “Have you ever been to 3111 World Drive in Orlando, Florida?” It would not be as easy for you to identify that I was referring to Disney World. You might be able to figure it out, but which is easier to use? In the internet world, 3111 World Drive would be the same as an IP address and Disney World would be the hostname. If you were to equate this to how the internet works, web hosting would be the equivalent of the real estate that Disney world sits on. When you purchase a website domain name, you must have internet real estate (website hosting) for your website to reside on, and conversely if you had website hosting without a domain name then no one would know where to go to access 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.

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.

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).

If you plan on having a web presence at some point, be sure to go ahead and register your website address now. There are many people and businesses that reserve the most desirable website addresses and resell them at costs much higher than the original reservation 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.
