$ ipcalc -b ${1-2-3-4}/${30}

try on your machine

The command you provided:

ipcalc -b ${1-2-3-4}/${30}

Explanation:

ipcalc is a command-line tool used for network management and calculating various IP address parameters.
-b is an option that specifies the output should be displayed in binary format.
${1-2-3-4} is a placeholder representing the IP address in the format "1.2.3.4".
${30} is a placeholder representing the subnet mask in CIDR notation. In this case, it represents a subnet mask of "/30".

Combining all the elements, the command will calculate and display the binary representation of the IP address "1.2.3.4" with a subnet mask of "/30" using the ipcalc tool.
