I need to increase the network address of a subnet, rather than increasing the ip address

ex: 20.20.20.1/24, the next should be 20.20.21.1/24, 20.20.255.1/24, 20.21.20.1/24 and so on. I have user NetAddr::IP, which only increments ip address. Is there any function to increment the network address 


      my $ip_add = NetAddr::IP->new('20.20.20.1/24');

            for (my $ip = 1; $ip<=2000; $ip++) {
                my $iponly = (split '/', $ip_add)[0];
                print "$iponly\n";

the above code prints from 20.20.20.1- 20.20.20.255
