A simple CIDR Network Calculator to help you calculate IPv4 subnet masks. CIDR stands for "Classless Inter-Domain Routing", and represents the preferred method of carving up IPV4 networks for the last 15 years.
This calculator was built from the ground up for trial and error and "what if" usage. It was made assuming you have a "history" command so you can recall the preceding command with the uparrow key and modify the preceding command as needed. So start with the bottom-most IP address you want to cover, and keep adjusting the maskbits figure (the number after the slash), until you cover all the IP addresses you want.
To use this calculator to find a small IP address group containing addresses between 192.168.47.21 and 192.168.47.67, issue the following command:
cidr-calc 192.168.47.21/24
This calculator was deliberately made to be easily used with trial and error, so you can get the range you want to get.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
On Arch Linux, snap can be installed from the Arch User Repository (AUR). The manual build process is the Arch-supported install method for AUR packages, and you’ll need the prerequisites installed before you can install any AUR package. You can then install snap with the following:
git clone https://aur.archlinux.org/snapd.git
cd snapd
makepkg -si
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
If AppArmor is enabled in your system, enable the service which loads AppArmor profiles for snaps:
sudo systemctl enable --now snapd.apparmor.service
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install CIDR Network Calculator, simply use the following command:
sudo snap install cidr-calc
Browse and find snaps from the convenience of your desktop using the snap store snap.
