It is recommended that a business or individual with a unique idea, design, concept or service on the Internet acquire ALL extensions (TLDs) available for identity and trademark protection & fraud prevention.

• .com — ("commercial") The most common extension for domain names. Often represents companies or for-profit organizations. Most personal Web sites also use this extension.
  
  
• .net — Generally represents Internet Service Providers (ISPs).
  
  
• .org — Usually represents non-profit organizations or groups.
  
  
• .biz — ("business") Reserved for use by businesses.
  
  
• .info — Made for both businesses and individuals. Usage is unrestricted, but a .info TLD indicates that the Web site primarily is informative.
  
  
• .ws — (Web Site) An all-around, universally available top-level domain.
  
  
• .us — Country-code top-level domain available for registrants in the United States.
