E' un programmino da shell che dato IP e subnet ti da molte informazioni pb# ipcalc Usage: ipcalc [options] <ADDRESS>[[/]<NETMASK>] [NETMASK] ipcalc takes an IP 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. -n --nocolor Don't display ANSI color codes. -b --nobinary Suppress the bitwise output. -c --class Just print bit-count-mask of given address. -h --html Display results as HTML (not finished in this version). -v --version Print Version. -s --split n1 n2 n3 Split into networks of size n1, n2, n3. -r --range Deaggregate address range. --help Longer help text. Examples: ipcalc 192.168.0.1/24 ipcalc 192.168.0.1/255.255.128.0 ipcalc 192.168.0.1 255.255.128.0 255.255.192.0 ipcalc 192.168.0.1 0.0.63.255 ipcalc <ADDRESS1> - <ADDRESS2> deaggregate address range ipcalc <ADDRESS>/<NETMASK> --s a b c split network to subnets where a b c fits in. Spero di esserti stato di aiuto Bye
