My favorite way: Open up your active network connection (under network connections), by double-clicking it, go to the support tab, click details. Then, l Hit the print screen button (right above insert, most keyboards), open up MS Paint, hit Ctrl-V and paste it in there, save that as “OLD IP INFO”.
That’s a great idea IRL too. I take pics of everything before I start taking something apart. The digital age has made life incredibly easier.
