The Internet Domain Survey is published on a biannual basis and has been conducted since 1987. Sponsored by the Internet Software Consortium, the survey "attempts to discover every host on the Internet by doing a complete search of the Domain Name System." In doing so, it serves as a key indicator of the growth of the Internet. This Web site provides results from each iteration of the survey. Additionally, the general methodology used to conduct the domain name search is explained. The number of hosts representing each domain (e.g. .com, .net, etc.) is also included.
