uni-cast IP trying to broadcast to link local address?

Dear Friends,

can this be explained, please.

(MAC is dummy)

34565 64.061324    dddd_67:8v:36        Broadcast      ARP    56        Who has 169.254.255.255? Tell 10.1.0.125 

this is an output from wireshark and what i understood is IP 10.1.0.125 is trying for mac with an arp request for 169.254.255.255

The 169.254.x.y looks like a device on your network that didn't get a DHCP address, and defaulted to the Microsoft APIPA address.  Could it be the 10.1.0.125 that somebody has altered, but left the original broadcast address in? 

Thanks you so much for your reply friend.

Yes that machine could be the one which doesn't got an IP from DHCP.

This can be because of DHCP not releasing the IP or there is a basic connectivity issue.

The point where in I am stuck is why this machine tried for an arp if the ip is not in the range of 10.1.0.125/24

If I am not wrong this can be same machines link local address, what do you say?

I am literally confused friend.
