This is a simple Android app that allows you to store IP addresses for all your hosts. Good for managing a network or homelab. It features storing IPv4 and IPv6 addresses, hostnames, and MAC addresses.
It uses a remote database to upload its files to, the source code of which is available here.
Note
This app was created for my CS 492 final. As such, it's far from a production-worthy build. I may revisit this app and flesh it out, but given how Google is putting Android into a "papers, please" era, I may cancel this plan.
Use the companion Python library to set up the database. Use your LAN or a VPN to expose it on your network. Download and install the app.
This app uses Sean Foley's IPAddress library.
