Cipher challenge

I was given a cipher challenge that has me a bit stumped.

A lot of the challenges I'm given are multi ciphers, but I can't get past step one yet for this one (my friends can get devious). The first clue is:

_ _ _ . _ _ _ _ _ _ _ _ _ _ . _ _ _


I know it isn't a latitude or longitude marking. It isn't a web address. It isn't a phone number. I was thinking Morse Code or Ascii, but that hasn't yield anything yet

Has anyone see a set of numbers / words displayed in this format? I know its a vague clue, but I was just curious if anyone had a thought about the format.
