I currently use Android IP scanner which is pretty barebones but works https://apt.izzysoft.de/fdroid/index/apk/com.victorb.androidnetworkscanner
Before that I used Vernet but it stopped working for me a while ago for unknown reasons https://www.f-droid.org/packages/org.fsociety.vernet/
Why is one going up and the other one going down? I assume the PS5 dude is returning the console to buy a coffee machine.
