Scan show wrong MAC

Hi!

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)

Regards:
Krzysztof.

Hello,

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)

Hi!

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