in thread ip range for config files

Thanks, after looking at Net::Netmask, it doesn't appear that it will accept an IP range:
192.168.0.1 - 192.168.0.100 and have 100 IP address returned...am I right? I also don't think NetAddr::IP will also. I think the formats are not compatible...

    The thing about 192.168.0.1 - 192.168.0.100 is that it is impossible to represent that exact range in one net block. You have to use several netblocks of varying sizes to do it. So no, Net::Netmask will not let you do it all in one block because its impossible.

    It does, however, give you the range2cidrlist method that will break that range into a series of valid netblocks for you.

      You know, I'll bet everyone using these modules wants the CIDR format...actually I don't. I want an array of individual IP addresses back from a CIDR format (or a IP-Range format)

      I want to give the user an option to specify a range of IP addresses in their favorite format and then get the array back...

      I am very likely very CONFUSED...

      Say I have a config file of hosts/devices to ping...

      # Ping me list
      host1; 192.168.0.1-192.168.0.10; 10.0.0.0/8; host2

      I am looking for a proper format to allow. right now, you have to list 1 IP or hostname on EACH line ;-(
