An extension, or Top Level Domain (TLD), is the highest-level category of Internet names. The domain name space is divided into several TLDs. The extensions .com, .net, and .org are called "generic" domains because they are not affiliated with any country. These domains are unrestricted, which means anyone can register as many .com, .net, or .org domain names as they like.
TLD's such as .info and .biz were recently introduced. These are examples of global Top Level Domains (gTLDs).
Country code Top Level Domains (ccTLDs), .ru (Russia) for example, are operated by separate registry authorities in 192 countries. Some ccTLDs have been opened by their respective countries to anyone looking for a creative alternative to a gTLD. For example, .tv (from Tuvalu) is now available for anyone who might want their Web extension to mean "television." And .ws (from Western Samoa) is open to anyone who might want their Web extension to mean "Web site." Some ccTLDs have restrictions on the name, amount you can register, or local presence. Others are unrestricted and can be registered just like .com, .net, and .org.
