apt-get install aptcalc
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
