How can I identify an Android device that's appeared in our scope

[speckytecky]

Checking our DHCP recently I noticed a few allocations that didn't have devices against them. I have identified most by entering the CURLallocated and seeing they come up as Wireless IP addresses. One however, just comes up as an Android device and I have no idea what it could be as I have certainly not joined any Android kit to the domain. How can I identify it?

If your using 2008 R2 (not sure about 2008?), enable DHCP filtering, stick the MAC into a deny filter and see who comes and complains their device doesn't work first?

 

I've done it with a couple of ipods/ipads but no one ever came to see me.....
