Abstract: We studied ASN assignments by the RIRs and the number of unique ASNs seen by routers on the Internet. The (net) growth rate of ASNs assigned by the RIRs is about 260 +/- 30 ASN/month. At this rate, all available ASNs will have been assigned between 2013 and 2016.

By comparison, the routing table only grows by about 195 +/- 45 ASN/month. We show that this is due to two effects: (1) ASNs which are assigned based on future plans but never used in practice, and (2) ASNs which are no longer in use but not returned to the RIRs. If all these unused ASNs could be recovered, the pool of ASNs would last until 2025 to 2030.

If not, then the ISP community should start to make plans for the deployment of 4-byte ASNs in the near future.

We will make some recommendations for ASN policy changes that would allow the RIRs to better allocate ASNs to end users.
