Here's an algorithm that doesn't suffer from the problem mentioned in the Note above:

my @list = ('10.1.1.[1..2]', '10.2.2.[1..2]', '10.3.3.[3..6]'); my @list_prime = map { my $n = $_; $n =~ s/\[(\d+)\.\.(\d+)\]//; [ $n, $1, $2 ] } @list; my @ordered_list; my $done; do { $done = 1; foreach (@list_prime) { next unless defined($_); if ($_->[1] > $_->[2]) { undef($_); next } push(@ordered_list, $_->[0].($_->[1]++)); $done = 0; } } while (!$done); use Data::Dumper; print Dumper(@ordered_list); __END__ output ====== $VAR1 = ''; # First from first. $VAR2 = ''; # First from second. $VAR3 = ''; # First from third. $VAR4 = ''; # Second from first. $VAR5 = ''; # Second from second. $VAR6 = ''; # Second from third. $VAR7 = ''; # Third from third. $VAR8 = ''; # Fourth from third.

It can probably be optimised.
