Duplicate IP addres from Sonicwall TZ-215

I have an Copper pipe which includes 60 usable Public IP Addresses.

Maybe 20 of them are actually in use; lets say 10.0.0.2 - 10.0.0.22 ( using local IPs for security )

I am currently getting intermittent connectivity on my network.

I assigned my laptop 10.0.0.2 and all other routers are assigned 10.0.0.x if x > 2 && x <=22

I am pinging the HP1810 switch, 10.0.0.3, and one router, 10.0.0.4. I am also pinging the Main Router IP, 10.0.0.1, the WAN serial IP, 192.0.0.1 and DNS, 4.2.2.2

From External I am pinging 10.0.0.3 and 192.0.0.1

When the issue occurs, I lose packets on my internal ping ONLY to 10.0.0.1, 192.0.0.1, 4.2.2.2. I do not lose packets on internal pinging to 10.0.0.3, 10.0.0.4, nor do the external pings show dropped packets.

It appears that something is clogging things up such as a broadcast, loop, or duplicate IP addresses.

I troubleshooted by running wireshark from my laptop on 10.0.0.2. I then ran an ipscanner to the subnet to get the ARPs back from them.

When I apply filter : expert.message contains "Duplicate IP address"

I see a lot of

Duplicate IP address detected for 10.0.0.z (xx:xx:xx:xx:xx:xx) - also in use by yy:yy:yy:yy:yy:yy (frame 149)

Now the MAC address xx:... correlates to a Sonicwall TZ-215 and z has been 10 different IPs and yy:... mac address has been 10 different MACs.

Is this what is causing my issues? the Sonicwall somehow fixing itself to multiple IP address on the subnet?

I also received the following:

582 7.423492000 Cisco_ xx:xx:xx Dell _yy:yy:yy ARP 60 Who has 10.0.0.2? Tell 10.0.0.15 (duplicate use of 10.0.0.15 detected!)

and

583 7.423559000 Dell_ yy:yy:yy Cisco _xx:xx:xx ARP 42 10.0.0.2 is at yy:yy:yy:yy:yy:yy (duplicate use of 10.0.0.15 detected!)

Now the Dell with yy:... MAC address is my laptop that sent out the ipscan and the Cisco xx:... is presumably a router with the ip address 10.0.0.15

What is that about as well?

Thanks for the help peoples!!
