The Netcraft Web Server Survey is a survey of Web Server software usage on Internet connected computers. We collect and collate as many hostnames providing an http service as we can find, and systematically poll each one with an HTTP request for the server name. In the January 1998 survey we received responses from 1,834,710 sites.

Netscape is the sum of sites running Netscape-Enterprise, Netscape-FastTrack, Netscape-Commerce, Netscape-Communications, Netsite-Commerce & Netsite-Communications.

Microsoft is the sum of sites running Microsoft-Internet-Information-Server, Microsoft-IIS, Microsoft-IIS-W, Microsoft-PWS-95, & Microsoft-PWS.

A facility for you to check what server a particular site is running now is also available. The same form can be used to ensure that a particular site is included in future surveys. A directory of sites running in developer domains is also provided, while the sites discovered by the survey can be explored.
