Dear monks, I need advice on how to deal with a large amount of ip addresses / subnets. I know there are modules out there, like Net::Netmask for instance, but I wonder if it could be achieved from core ? This is not a constraint, I'd like to have a discussion on this matter. For searching / matching purposes : Let's say I build a hash where the level would match the octets. Something like a tree ... Given IP addresses : ( 10.10.10.1 , 10.11.10.1, 11.10.0.1) The first level would contain 10 and 11, but the second level of 10 would contain 10, 11 and so on. Is this a good approach ? I know my whole question is not clear. I'm still confused. Best regards, Luc
