The first link that contains a link to take me to a ip scanner for Apple tells me that it is unavailable in my region. I did find another one and also used arp cmd to view everything and am not seeing anything I have not tried to connect to yet.
I am only able to connect to two ips, the one that you are saying is connecting me to the switch only(192.168.1.19). The other just displays a page coming from my ISP(Spectrum:192.168.1.1). I also logged into the spectrum app which shows me all the historical connections, which I can see the 3 AP's that were there and the switch with the same ip as the one I am able to connect to currently.
