What could be the reason for the periodic switching to a foreign IP address of a series of computers?

Question

Iron

With the help of a long analysis of the activity of computers on the local network from the server, I found that some computers in my park are found on the IP address 192.168.0.10. The strangeness is also expressed in the fact that such a mess occurs only with Acer monoblocks of the Veriton Z2611G model. That is, out of a hundred computers, only about a dozen appear at this address and occupy it, so it is impossible to install any other computer at this address, swearing at an address conflict. I must say right away that I exclude virus activity, this is unrealistic, because of all the computers I detect ONLY Acer monoblocks. There are suspicions that this is a problem in network cards or the assembly of Windows that works on them (as they were installed and placed on the network, nothing has changed dramatically on them, the native operating system is installed (Windows 7 Professional). Perhaps this can push to the right decision, but when the computer that occupied the IP is detected, this happens using an ARP request, not ICMP, and the scanner (in my case, SoftPerfect Network Scanner) except for the MAC address (due to which it turned out that they occupy monoblock address) and IP addresses cannot find out anything at this moment, as if this computer occupied the IP address 192.168.0.10 for a moment and then "hooked up". In general, I don’t even know what to do here, and most importantly, what is wrong with the settings of these monoblocks? that the address is occupied by monoblocks) and IP addresses cannot be found out at this moment, as if this computer occupied the IP address 192.168.0.10 for a moment and then “hooked up”. In general, I don’t even know what to do here, and most importantly, what is wrong with the settings of these monoblocks? that the address is occupied by monoblocks) and IP addresses cannot be found out at this moment, as if this computer occupied the IP address 192.168.0.10 for a moment and then “hooked up”. In general, I don’t even know what to do here, and most importantly, what is wrong with the settings of these monoblocks?

IMPORTANT NOTE : In the entire park, computers have static addresses, DHCP servers are not raised anywhere and are not found inside the network. Therefore, random assignment of IP addresses should not be considered here.

Answer 1

This is ASF
. Turn it off in the BIOS, and it will not raise this IP-shnik.

Answer 2

You can set an alternative ip address in the connection properties. He's not there?
