Domain names allow individuals or companies to post their own websites, have personalized email addresses based on the domain names, and do business on the Internet. Examples of domain names are webpromax.com and livestrong.com. When you put up a website, the web-hosting company provides an Internet Protocol address, which is a set of numbers that pinpoint your site on the Internet. It is possible, however, to supply your own IP address, called a static IP. This can provide flexibility for gamers, allow web hosting from your computer or make connecting to a virtual network simpler.
