WHAT'S A DOMAIN NAME?

A domain name is a way to identify and locate computers and resources connected to the Internet. No two organizations can have the same top-leveldomains.com. 

Every company or organization or individual that wants to be on the internet will register a domain name for use as their on-line identity or name that clients (customers, all internet users) will use to access on-line services such as the organization's website or email system. For example, MyDiscountDomains.com registered the domain name MyDiscountDomains.com, so users on the internet can access our website (and order services, etc) at www.MyDiscountDomains.com and send email to MyDiscountDomains employees at username@mydiscountdomains.com. Much like a company's name, logo, or 800 number, a domain name has marketing value when customers can easily remember and associate it with the organization. Since over 150 million domain names have already been registered world-wide, it can be difficult to find a good domain name. MyDiscountDomains.com offers tools to help you find domain names and will help you through the processes of registering a domain and setting up a website for your business or organization. 

Each domain name corresponds to numeric IP (Internet Protocol) addresses. An IP address takes the form of 4 numbers, each one between 0 and 255, separated by periods. The Internet uses the numeric IP address to send data. For instance, you may be connecting to a World Wide Web server with the domain name "theredsea.com", but as far as the network is concerned, you are connecting to the Web server with the IP address associated with that domain name. 

The Domain Name System completes the task of matching domain names to IP (Internet Protocol) addresses. Domain names, and their corresponding IP addresses, must be unique. If more than one organization on the Internet had the same domain name, confusion would occur when the network tried to identify and communicate with the computers within those organizations. For example, if there were two separate universities, one in Maine and one in Arizona, they cannot both use the domain name "coolschool.edu", because the Domain Name System would not know which one of the universities' IP addresses were associated with that domain name. 

The Domain Name System is a collection of databases that contain information about domain names and their corresponding IP addresses. Domain name servers are computers that translate domain names to IP addresses. This system allows Internet users to deal with the more intuitive domain names, rather than having to remember a series of numbers.
