As typically represented, MAC addresses are recognizable as six groups of two hexadecimal digits, separated by hyphens, colons, or without a separator.įor example: 12:34:56:78:90:ab. Within the Open Systems Interconnection (OSI) network model, MAC addresses are used in the medium access control protocol sublayer of the data link layer. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth.

Not exactly what you're looking for, but definitely on the right track.A media access control address (MAC address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. You could also do something similar to the verified answer. Sniff(prn=arp_monitor_callback, filter='arp', store=0) Return pkt.sprintf('%ARP.hwsrc% %ARP.psrc%') If ARP in pkt and pkt.op in (1,2): #who-has or is-at You must either call a system command such as arp to get ARP information, or generate your own packets using Scapy.Įdit: An example using Scapy from their website: As mentioned in the answer chosen by the asker of that question, Python doesn't have a built-in way to do it. There was a similar question answered not too long ago on this site.

> # The time between ping and arp check must be small, as ARP may not cache long Knowing that, you do a little subprocess magic - otherwise you're writing ARP cache checking code yourself, and you don't want to do that: > from subprocess import Popen, PIPE That will place the target - as long as it's within your netmask, which it sounds like in this situation it will be - in your system's ARP cache.

A small change to the regular expression will make it work in OS X.įirst, you must ping the target. I don't have Windows handy, so the following solution works on the Linux box I wrote it on. To answer the question with Python depends on your platform.
