iPhone contacting a sinkhole

["McClenon, Brady" <Brady.McClenon () ONEONTA EDU>]

We have received three alerts from REN-ISAC in the last month or so about an address on our network contacting a 
sinkhole.  In each case the device was a student's iPhone on our residential network (a different student in each 
case).  I'm curious if anyone else has seen this and if they have had any luck determining what is causing it.

Thanks,
