I don't know of any modules that do exactly as you want with IP addresses. But it is useful to note that IPv4 addresses can be packed into a 32 bit integer, so ranges of IP adresses can be mapped into ranges of integers. Then you may use a module called Set::IntSpan to manipulate ranges to your hearts content: 
  use Set::IntSpan qw(grep_set map_set);
  
  $Set::IntSpan::Empty_String = $string;
  
  $set    = new   Set::IntSpan $set_spec;
  $valid  = valid Set::IntSpan $run_list;
  $set    = copy  $set $set_spec;
  
  $run_list = run_list $set;
  @elements = elements $set;
  @spans    = spans    $set;
  
  $u_set = union      $set $set_spec;
  $i_set = intersect  $set $set_spec;
  $x_set = xor        $set $set_spec;
  $d_set = diff       $set $set_spec;
  $c_set = complement $set;

# and many more methods

Also there are the modules Array::IntSpan and Array::IntSpan::IP which also manipulate ranges in an array context, but don't seem quite as flexible as Set::IntSpan.
