This plugin offers a place to retrieve

• A table with the CIDR to netmask conversion, inluding the wildcard bits and the total hosts available per CIDR
• A tool to convert a CIDR into an IP range including information such the usable host count, the netmask in decimal dotted format and the wildcard bits

Install

The plugin is available as a Python package and can be installed with pip.

Run pip install netbox-ipv4-tools in your virtual env.

Create a file named local_requirements.txt (if not already existing) in the NetBox root directory (alongside requirements.txt) and list the netbox-ipv4-tools package:

# echo netbox-ipv4-tools >> local_requirements.txt

Once installed, the plugin needs to be enabled in your configuration.py

# In your configuration.py

pip3 install netbox-ipv4-tools
python3 manage.py collectstatic --no-input

Thanks to rs for the work on netmask
Thanks to mattieserver and his project netbox-topology-view. I used his work to get a working plugin and to publish it to pypi
