Com, .net, .org, .biz, .edu, .info, .int, .GOV, .mobi, .aero. For many unsuspecting Internet surfers, these dot whatever mean no greater than being an extension name of the websites they are visiting. They do not realize that these three letters coming after a period or dot serve a great function in the webbed world of Internet.
Top-level domain or the last part of an Internet domain name serves as virtual, invisible fences in the immeasurable vast space of Internet. They denote classification and stratification. Top-level domains tell us the kind of website we are about to visit. .com is for commercial websites open for everybody to visit and register on, .biz is for businesses, .edu is for educational institutions (mostly schools, colleges, and universities), and .gov is for governmental agencies and entities. Each top-level domain corresponds to a certain association or classification in an attempt to organize the seemingly-impossible-to-organize portals of the Internet.
One of the latest addition to the list of approved top-level domains is the .travel domain. It was in May of 2005 that the idea of a top-level domain for the travel industry came about when the Internet Corporation for Assigned Names and Numbers (ICANN) approved the contract proposed by Tralliance to operate the administration of a top-level domain for the booming travel industry. Tralliance is a company that develops products and services to promote the efficiencies and convenience of e-commerce for the global travel and tourism industry. It’s headquarters is in New York.
