  <p>I need to create a dictionary, for each i in A, the lenght of A, C, D and E.
  For example:</p>
  
  <pre><code>10.12.13.16 appear 2 times, with
       [C : 604, D: 2345, E : 4572] and [C : 3300, D : 3456, E : 5664]
  10.24.35.14 appear 4 times, with
       [C : 200, D: 9753, E : 75498] and [C : 360, D : 9874, E : 56789] and 
       [C : 740, D: 4563, E : 7643] and [C : 634, D : 0867, E : 8754]
  16.22.27.11 appear 3 times, with
