I noticed today that there are a large number of devices on my home network, all claiming to be ethernet connections. They kind of claimed all free IP addresses from x.x.x.63-253. They are not all on from what I have seen (and they are currently almost all off). Normally, my network should have only a handful of ethernet devices, which are my Fedora desktop, my Proxmox host, my OpenMediaVault VM on Proxmox machine running 24/7, and then the occassional VM I boot up as needed. I searched the occasional MAC address of one of these devices, and nothing came up. Does anyone know what the culprit of this would be or what I could use to diagnose it?
