An ipv4 netmask/broadcast/etc cgi calculator
ipcalc should be called as a CGI application from a web server.
ipcalc_cgi is the web based version of ipcalc. It takes an IPv4 address and netmask and calculates the resulting broadcast, network, Cisco wildcard mask, and host range. By giving a second netmask, you can design sub- and supernetworks. It is also intended to be a teaching tool and presents the results as easy-to-understand binary values.
