IPv4 to binary

// Converts IPv4 to binary representation

>_ netcalc "192.168.150.1" -2
>_ netcalc "192.168.150.1" --ip-to-binary

// result ---> [ '11000000', '10101000', '10010110', '1' ]

Min and max address

// Calculate min (network) and max (broadcast) by IPv4 and CIDR

>_ netcalc "192.168.150.1" 24 -r
>_ netcalc "192.168.150.1" 24 --range

// result ---> ['192.168.150.0', '192.168.150.255']

Range of a network

// Calculates all IPv4s between and including the provided min and max addresses.

>_ netcalc "192.168.150.1" "192.168.150.254" -i
>_ netcalc "192.168.150.1" "192.168.150.254" --inner-range

// result ---> ['192.168.150.0', '192.168.150.1', '192.168.150.2', ..., '192.168.150.254', '192.168.150.255']

CIDR to netmask

// Converts CIDR to netmask

>_ netcalc 24 -c
>_ netcalc 24 --cidr-to-netmask

// result---> [255, 255, 255, 0]
