There's plenty of valid reasons to configure a static IP address, I'd say I do it weekly. Configuring a commonly used machine to be static for ease of use. Connecting a TCP communication device (barcode reader, RFID reader, etc.) direct to your computer for testing. Just as a couple examples.
Yeah and you can still make a static IP with Windows 11. This is bullshit M$ whining. Shit changes. Explain to me why Debian fucking around with "ip" is less destructive.
