ipcalc: Show information about an address or network in CIDR notation.
$ ipcalc ${1-2-3-4}/${24}
try on your machine
The command "ipcalc ${1-2-3-4}/${24}" is a bash command that uses the "ipcalc" utility to calculate certain details about an IPv4 address and subnet mask.
Here is the breakdown of each component in the command:
- "ipcalc": This is the name of the utility being used. It is usually installed in Linux systems and is used to manipulate and calculate network-related information.
- "${1-2-3-4}": The command uses a positional parameter (${1}) to represent the IPv4 address. In this case, it assumes the IPv4 address is specified as 1.2.3.4. You can replace this with an actual IPv4 address.
- "/${24}": This represents the subnet mask or network prefix length. The "/${24}" notation signifies a subnet mask of 24 bits or a network prefix length of 24. Again, you can replace this with an actual subnet mask or network prefix length.
When the command is executed, it performs calculations using the given IPv4 address and subnet mask. This can provide information such as the network address, broadcast address, host range, and more.
Note: It's worth mentioning that this command assumes you have the "ipcalc" utility installed on your system. If it is not installed, you may need to install it first using package managers like apt or yum.
