Now we'll examine the name itself.
Domain names have at least two parts, separated by a dot or period.
The Top Level Domain serves to broadly categorize the name as to its type or purpose. Domain names ending in .firm, .store, .web, .arts, .rec, .info, .nom and possibly many others will become widespread on the Net. Further left SLDs identify locations and institutions and maybe host machines. Databases of domain records are maintained by InterNIC, the primary name registry on the Internet in the US, and by a variety of similar agencies throughout the world.
