You really need to find the "other" 10.0.1.180 & 181 to work it out. Teaming interfaces can have IP duplicates, but only as a source address. Other possible causes are a router configured with proxy ARP enabled, but the wrong network mask.

Hi,

Teamed network interfaces, maybe?

Thanks,

I was running a scan and started to notice these summaries:
 
AsustekC_ad:e3:e7     Dell_80:75:35     ARP     10.0.1.35 is at 00:1a:92:ad:e3:e7 (duplicate use of 10.0.1.180 detected!)
Dell_9d:29:af     Dell_80:72:79      ARP      10.0.1.230 is at 00:23:ae:9d:29:af (duplicate use of 10.0.1.181 detected!)
 
I have done the obligatory research to see if there is a duplicate IP on the network and could not find any.
 
Anyone know what this message means?
 
Thanks
