How your Billing Score is calculated

Information about how the RIPE NCC calculates billing scores for its members.

To determine a billing category, a score is calculated based on Aggregatable Internet number resources made to a member over time.

The score of an allocation is calculated by multiplying the scoring unit for that resource (for example: scoring unit 4 for an IPv4 /19) by the age of the resource (based on a time function: year of the allocation minus the year 1992). The total score (i.e. billing score) is the sum of allocation scores.

The table with the scoring units is in the RIPE NCC Charging Scheme 2011.

The table above shows how scoring units are determined based on resource usage. To establish scoring units based on larger or smaller resource usage, the same ratio applies.

N
S (reg) = Σi=1 ai * ti
a i= Scoring unit
t i = Time function of allocation (year of allocation -1992)
N = Number of allocations

In simplified terms:

  • Score = Scoring unit an allocation is worth
  • Time score = Time function of an allocation (year of allocation - 1992)
  • Score X Time score = Allocation score

The total score per Member is the sum of all allocation scores.

 


An Example

Based on the billing score boundaries represented in the table below, this LIR is classified in the SMALL billing category for the year 2011.
