An Internet domain name server platform which intercepts web browser HTTP queries to unrecognized, unregistered subdomain name and provides redirection of the query to a recognized and registered domain name or a subdirectory of a recognized and registered domain name. A server script is launched in response to the event of the request to an unrecognized subdomain name, which dynamically resolves the unknown address rather than returning a standard "Error 404: File Not Found" message to the requesting web browser. The script accesses a database of virtual subdomain names which are mapped in the database to actual subdirectories on the same or a remote server. For example, if a query to http://www.virtualsubdomain.domain.com is received, and virtualsubdomain.domain.com is not recognized as a registered domain name by the standard DNS server, the script will resolve it and map it to http://www.domain.com/subdomain, or any other file on a web server which is actually registered. Using this method, the creation of a virtual subdomain requires only the steps necessary to create a subdirectory. This enables it to be performed rapidly if handled manually, or it can be created automatically by any network client with privileges to create subdirectories on the web server in question.
