Website And Domain Names

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.

When you lookup websites online, your web browser talks to web servers via their IP address. Advances in technology have made it possible to assign words or hostnames to ip addresses. PC's use operating systems like windows or linux operating systems. These operating systems use something called a host file to translate the words into IP addresses. On a Windows computer the host file is stored in the c:\windows\system32\drives\etc\ directory; on Linux and Unix servers the host file is kept 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.

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.

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).

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.

Make sure you control your own internet destiny. Never let your web designer or web design store reserve your website address in their name. By purchasing your domain name yourself, you secure your own interest in your website address and you protect yourself from negligent people and predators looking to take advantage of you.
