IP Addresses

This script prepares an image enumerating the IP Addresses of the host limited to IPv4 addresses.

This can be especially useful to raspberry pi operators using an attached screen that setup their device to use DHCP vs a statically assigned IP from their router. As the IP addresses changes, the images generated can reflect such changes affording easier ability to login over local network. It can also be helpful to see what IP addresses are bound as listeners for local virtual networks typically setup with Docker.
