### Continual ARP Requests

Hello, everyone. I'm new to Wireshark, so this may be a stupid question. I'm seeing my router continually ARP-ing an IP address that appears to be the same as my public address except for the last octet (after the last period). The message is the following: 46.853880 Tp-LinkT_24:23:b4 Cadant_6f:68:46 ARP 60 Who has 73.207.128.1? Tell 192.168.0.1

I read an answer to a similar question, but it didn't make sense to me. My set up is very simple: a router with Wi-Fi capabilities with two Ethernet connections + whoever is connected to Wi-Fi at the time (my phone, my wife's phone, my daughter's laptop and phone). I have strict access controls, so there are no unauthorized devices. I can account for everything when I access the router and check everything that is connected - nothing but the whitelisted devices that I configured myself. Such behavior of the router is obviously not normal. Is the router ARP-ing the modem itself for some reason and the model does not respond? I may be just talking gibberish right now... as I said, I'm new to WireShark and don't have a deep understanding of networking yet (but trying to learn).
