Hi all, I have a list of subnet: http://pastebin.com/e9LPv55K (These are Google IP ranges lokked up from his AS#) Some consecutive/adjacent "/24" could be "/23"'d and even multple consecutive "/24" coudl be "/18"'d and so on... Have you got in your bookmarks or notes some IP adresses manipulation functions, so that I could shorten that list? I would like to make that exercice in OCaml. Thank you. -- RMA.
