Using wireshark I have found that one PC on my network constantly scans for devices on the network using ARP, e.g.
Who has 192.168.0.26? Tell 192.168.0.10
It does that approx. 2 times a second and asks for a lot of
192.168.0.x addresses where x is in the range 0 to 30.
I'm wondering what program that would do something like that?
Also I'm wondering if there could be a security problem involved.
The PC in question runs windows 7.
