This reminds me of back when Apple sold WiFi access points (they were high-quality, but a pain to administer since they required running a Windows-only or a MacOS-only executable). I tried running arpwatch for a while on a network which had one of these, and gave up, since the MAC address for any Apple machine on the network was constantly bouncing between the real machine and the access point. Apparently, whenever an Apple desktop went to sleep, that WiFi access point proxied ARP and mDNS requests for it, much like what's described on this post (but it did that by default, with no configuration required to enable it).

- deltarholamda 4y agoThey were high-quality. I used one for years, even had a hard drive attached for a while for Time Machine backups, which worked well. I had to stop using it for some reason--it wasn't getting updates, or newer WiFi cards weren't working well with it, something--and everything I've used since has been disappointing. Even at the price point of the AirPort, they all have various issues. I wish this technology was a done thing.
