Size and Scope of the Internet 
          
            Internet Domain Survey, conducted 
              by Network Wizards and sponsored 
              by the Internet Software Consortium. 
              The latest survey in July 2001 showed an estimated 125.9 million 
              hosts on the Internet. Breakdowns by country domains is available. 
              Historical data from pervious surveys is also available (see Lotter's 
              RFC 1296).

The Netcraft Web Server 
              Survey. Netcraft collect and collate as many Internet hostnames

              survey they received responses from 1,044,163 sites, rising to 11,161,854 
              sites by February 2000 and up to 36,689,008 in January 2002.
