Hi,

in the thread referenced by you there is an answer from BrowserUK (Re: Iterating through all IP addresses in a CIDR) where he presented a solution to enumerate every Host-IP in a subnet. When you build up a hash with all generated hosts you can check your IP addresses with a exists lookup into that hash.

You need memory for that. But in your list you didn't say you don't have that. :-)
