I'd like to inlcude a category in the ASNumber tooltip which lists
the number of listed IPs within that AS per RBL. It'd look like this:
SBL: 5835/5
XBL: 2645/3
SCBL: 3864/4
[numbers made up..., the second number is the average of listed IPs
per /24 announced by the AS]
Entire netblocks do not count as one but as many IPs they span.
