Wireshark-users: [Wireshark-users] Duplicate IPs

From: "Josue Del Valle" <jodelvalle@xxxxxxxxxxxxxxx>

Hi,

 

I hope someone can help me out with this.  I am running Wireshark from two different computers and getting the same results.  Basically I am getting the following:

ARP/RARP Duplicate IP address configured (192.168.10.222)

ARP/RARP Duplicate IP address configured (192.168.10.220)

ARP/RARP Duplicate IP address configured (192.168.10.208)

 

This is an example:

154,"16:58:24.071822","Dell_55:3b:5b","Dell_42:b5:3a","ARP","Who has 192.168.10.40?  Tell 192.168.10.222 (duplicate use of 192.168.10.200 detected!)"

 

 

These addresses are statically assigned and I don’t see how they could be duplicated.  I read that this could be an ARP attack but I’m not sure what to look for.

How can I know whether it is an ARP attack and trace the computer that’s causing the problem.

 

 

 

 

Regards,

 

JD
