Anyone have a tool to turn a list of IP addresses into a list of CIDR networks, using WHOIS or routing data. Just I have a list of 2000 IP addresses which we've identified as abusive in the last 2 weeks, and much of it is coming from limited number of server providers, and well it is getting to the point where it is tedious manually, and I figure it is a wheel that doesn't need reinventing. Probably someone has a tool which compares number of addresses to size of block, and does the "right thing" based on percentages or some such. Then again a good blocklist for web comment spam would probably do instead, but haven't found one of those yet either.
