I operate such a network and that’s totally normal. I
wish there was something like proxy ARP on the CMTS to mitigate that spurious
traffic.

Subject: [Wireshark-users] ARP Broadcasts
I have broadband through my cable company. I unplugged the
router and plugged my computer directly into the cable modem and ran wireshark
to see what I would see.
What I see most is almost non-stop ARP broadcasts coming from the gateway and
going to all sorts of ip addresses, "Who has <ipaddress> Tell
<ipaddress>"
Is this normal? Should I be picking this up? What kind of network would result
in me getting all these ARP packets?
Thank you.
