Scan show wrong MAC


I have found some interesting case in my network. Hope somebody could logically explain it.

Situation is as follows:
One linux box (debian Linux) have two network interface. One called eth0 with IP A.B.C.33 and MAC xx:xx:xx:xx:xx:48 and second one, eth1 with MAC xx:xx:xx:xx:xx:49. eth0 is on VLAN 1 and eth1 has 3 IPs, each on different VLAN (101, 102, 102) and none IP on VLAN 1. When running Advanced IP scanner it detects IP A.B.C.33 with MAC xx:xx:xx:xx:xx:49 instead of xx:xx:xx:xx:48.
But arp table on computer where Advanced IP scanner was running shows correct MAC xx:xx:xx:xx:xx:48.

I could not understood nor explain this! Does anyone have any theory why this happen? (on the linux box there is no bridging)

You need to delete stored data. You can find this option in the following way: Advanced IP Scanner -> Settings -> Options -> Misc -> Delete stored data.

Reset cache
Delete this file, it path here:
C:\Users\user_name  (advanced_ip_scanner_MAC.bin)

I have done as you said, but this does not change anything. IP scaneer still shows wrong MAC for this given IP.
