I’m noticing two machines that have been assigned addresses via DHCP with neither device displaying its name. Obviously, neither is listed in DNS.
One of these machines has attacked another computer on the subnet according to a recent alert.
I only have the MAC addresses to go on at this point.
Before going to the switch and tracking them down…
Is there a good, free utility that I can run against the IP addresses to find the OS type or other additional information of these machines?
