The video shows how to find IP address in 192.168.0.x network for known 00-0C-29-01-7C-3F MAC address from command line window:įirstly checking ARP cache if it already contains a record for MAC 00-0C-29-01-7C-3F: arp -a | find /i "00-0C-29-01-7C-3F" The file is small and simple in use but can be used in networks 255.255.255.0. Please note for statement uses double percentage sign – that’s correct for batch files. MAC address to search expected in command line argument: off Waiting for 15 seconds or more can result in some ARP records will be dropped.īelow is a batch file ip_by_mac.cmd to perform these actions. Then run arp -a immediately after loop finishes. characters before start hides output from 254 ping processes.If type just do ping without start the loop will take about 10 minutes. all ping processes will start at the same time (not waiting for another ping finishes) so it will take only several seconds.Important that ping utility processes would be started with do /b ping because: The simplest way is to ping all possible IP addresses in the LAN.

To get full list of ARP records one can use standard ping utility. That means a record related to the particular MAC address could be deleted and therefore unavailable. The main reason for that is Windows keeps ARP cache records for 15-45 seconds, see Address Resolution Protocol (ARP) caching behavior in Windows Vista TCP/IP implementations for more details. This is simple but the record for a particular address may not present in the list. Same question may be for remote computers.Ī simple way to find IP address works on any PC and requires no administrative permissions – find IP address from ARP cache list by filtering the list by known MAC address: arp -a | find /i "01-23-45-67-89-ab" May be a device has a static IP address configured but we can’t remember it while MAC address is known (labeled on the box). For example we connected such a device to a network with DHCP and we’d like to know what IP address the device got from DHCP server.
This is mostly problem for network devices like network printers or IP CCTV cameras.
Sometimes it is needed to determine IP address of a network device or a PC but only MAC address is known.
