As you know my internet has been complete SHIT for the last few weeks. I've finally managed to get Wireshark downloaded and I'm using it to look at network traffic. What I see is one computer sending ARP requests to all the addresses on my subnet every other seconds.
There are ARP requests being sent for any address on 10.183.8.*

There seems to be only one computer doing this. I'm wondering if this would be enough to cause network problems IF the network is running over a WI-Max connection to a server. If it is, is there any easy way to stop it as a user on the network?

Is that host your gateway?

Cause if so, thats what a gateway does.

ARP binds physical addresses (MAC) with protocol address (IP). So the gateway is just running around asking all the IP addresses if anyone is there (using that IP address). This will happen whether they're a newly connected host or not.

This polling method would be less important if every host supported protocols like DHCP (where the host actively requests an IP), but still important in case hosts are removed / moved.

So basically, thats how it works and there's nothing you as a host can do or really would want to do for that matter.

I don't believe it's the gateway. According to Wireshark the MAC address throwing the ARP packets is a Dell device. There's also a Cisco device that throws a bunch of ARP requests to everyone, but it waits a couple of minutes in between. The Dell MAC is throwing the ARP reqests every other second.
