Potentially a huge number (if you are getting DDOSed ;). Yes, basically it works that way. The only exception is 0.0.0.0/0: "A special subnet is "0.0.0.0/0": All data is stored in the src_bytes and src_packets structure of slot "0". This is useful if you want to account the overall traffic to/from your internet provider." -> You can accumulate complete subnets on one entry if you like. F.e. we use this to check for network activity (=and decrase a timeout if not present).
