^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

 I guess that 'cpe-109-55-115-44' (with single quotes) would work fine, 
 since it is an atom.  However, cpe-109-55-115-44 is not an atom and, 
 with the minus sign, is not a valid expression, either.

 It appears that your computer's hostname is getting set to the ISP's
 name for your location.  "Customer Premise Equipment ..." with your IP.
                          ^^^^^^^^^^^^^^^^^^^^^^
                          cpe-190-blah blah

 If you change your hostname to a valid erlang expression, then your
 "erl -sname base" should work fine.
