ipcalc
IPCALC(1) RH IPCALC(1) NAME
ipcalc - perform simple manipulation of IP addresses SYNOPSIS
ipcalc [OPTION]... <IP address>[/prefix] [netmask] DESCRIPTION
ipcalc provides a simple way to calculate IP information for a host. The various options specify what information ipcalc should display on standard out. Multiple options may be specified. An IP address to operate on must always be specified. Most operations also require a netmask or a CIDR prefix as well. OPTIONS
-b, --broadcast Display the broadcast address for the given IP address and netmask. -h, --hostname Display the hostname for the given IP address. -m, --netmask Calculate the netmask for the given IP address. It assumes that the IP address is in a complete class A, B, or C network. Many net- works do not use the default netmasks, in which case an inappropriate value will be returned. -p, --prefix Show the prefix for the given mask/IP address. -n, --network Display the network address for the given IP address and netmask. -s, --silent Don't ever display error messages.
