Some facts from today.
Ordered capacity 3.3Gbit
Received capacity ~2.1Gbit if they apply bandwidth limit
In this example they removed limit, but you can have approximate picture 
how bandwidth is distributed (top 20 ips):

Average packet size 834 (with ethernet header, max avg sz 1514)
Time 6748, total bytes 2753819139, total speed 3188235 Kbit/s

As you can see max single ip takes is 4.48% of bandwidth.
Also i cannot waste ipv4 for larger pools, just because of some deadly
flawed equipment/configuration.
