I realize it's not quite that simple due to issues of longer prefixes taking precedence over shorter ones, but it is my impression that there's a lot of sloppiness.

16M /24 is just a cheap 16M entry SRAM. However, 16M /32 means 4G entry SRAM or 16M entry CAM. 16M entry with /40 or /48 prefix means 16M entry CAM, which is hard, which is why IPv6 is hard. Masataka Ohta
