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.
