At present, using with HTML5 and new browser technologies, many information, such as a hostname or a server application name, can be collected by a Web server. Even if the visitors are protected by a firewall, their intranet information can be collected. Then, currently people should also focus on the intranet information where he or she belongs to. In this paper, we propose a network scanning tool that allows a Web browser to collect information about active hosts or the existence of a proxy over a channel to the Web server.
