Key-value database with search by cidr

[MonaxGT]

Hi Yulin Chen!

Do you have any ideas how to create some key-value database where key is a cidr or some algorithm to fast find occurrence of an address in network?

For example: You have a lot of network with various masks and some data about this networks. You try to find in which network this address exist and return data. I don't want iterate over in a loop all key-cidr and try to find solution with your cidrranger decision
