Can I determine the current IP from a known MAC Address?

Question

I have a shell script which uses etherwake to wake up a machine on my local network. After the machine is awake, I\'m not sure of the IP address.

While trying to answer

Answer 1

I wrote a python module that can do this:

>>> from ethip import ethip
>>> print ethip.getip('00:1E:C9:56:3C:8E', '10.5.42.255')
10.5.42.3

I just makes rapid arp requests to find the ip, then caches what it finds. The code is on github.
