Nice dhcp client you have in them there Apple TV's:
Address HWtype HWaddress Flags Mask Iface 10.0.17.104 ether 2c:b4:3a:aa:bb:cc C wlan0 10.0.13.14 ether 2c:b4:3a:aa:bb:cc C wlan0
Neat trick making the same network device have 2 ip addresses.
And by "neat", I mean, completely broken and stupid!
Fix your stuff idiots.
Yes, I changed the last bits of the mac address to protect the innocent, but I assure you they were the same.
Seems like others have found this to be a bummer as well: Princeton write-up
