"When I despair, I remember that all through history the way of truth and love has always won. There have been tyrants and murderers and for a time they seem invincible, but in the end, they always fall — think of it, always." Mohandas Gandhi
In a time of universal deceit - telling the truth is a revolutionary act. George Orwell

IPcalc - uma bela ferramenta de redes

$ ipcalc
Address: 11000000.10101000.00000001. 00000010
Netmask: = 24 11111111.11111111.11111111. 00000000
Wildcard: 00000000.00000000.00000000. 11111111
Network: 11000000.10101000.00000001. 00000000
HostMin: 11000000.10101000.00000001. 00000001
HostMax: 11000000.10101000.00000001. 11111110
Broadcast: 11000000.10101000.00000001. 11111111
Hosts/Net: 254 Class C, Private Internet

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 subnets and supernets. It is also intended to be a teaching tool
and presents the subnetting results as easy-to-understand binary values.

Enter your netmask(s) in CIDR notation (/25) or dotted decimals (
Inverse netmasks are recognized.
If you omit the netmask ipcalc uses the default netmask for the class of your network.

No seu site, também existe a funcionar como ferramenta online.

Para utilizadores como eu de Debian e Debian based, como o Sidux, Ubuntu e derivados, está a um $sudo aptitude install ipcalc

Nota: em Sidux não se deve usar o aptitude mas sim o apt-get
