Iterate through ip address range in perl

Question

I have to iterate through a range of ip addresses in perl and print a list of all ip's in that range. for ex - for

192.168.122.1-192.168.122.4

My return value is

192.168.122.1, 192.168.122.2, 192.168.122.3, 192.168.122.4

Also I cannot use Net::IP or Netmask modules, so finding other ways to iterate.

Following solution works but has some problems i cant seem to figure out -

1 - my start and end would be perl variables "" and not as mentioned in the code below. The code below doesnt work with start="192.168.122.1"

2 - How can i get a list of all ips appended at the end?

sub inc_ip { $_[0] = pack "N", 1 + unpack "N", $_[0] }
my $start = 192.168.122.1;
my $end = 192.168.122.4;
for ( $ip = $start; $ip le $end; inc_ip($ip) ) {
    printf "%vd\n", $ip;
}

You seem to want:

use Socket 'inet_aton';
my $start = "192.168.122.1";
my $end = "192.168.122.4";
my @x = map { sprintf "%vi", pack "N", $_ } unpack("N",inet_aton($start)) .. unpack("N",inet_aton($end));
use DDP; p @x;
