The chart enclosed on the left presents the distribution of /8 prefixes (status on 22.08.2010). As expected the biggest number of /8 assignment is to the ARIN registry (~40% of the total number of IPv4 /8 prefixes). The numbers of prefixes for APNIC and RIPE are very closed together - although last year RIPE was ahead of APNIC. The important information is that there is still 13% (32 prefixes) available to be assigned for further IPv4 development.
A very valuable information 
is how the utilization of the IPv4 prefixes looked over time. There is a figure, which shows the statistics retrieved from the RIRs from th 2003 till now (22.08.2010). One can easily notice that for all RIRs the number of assigned IPv4 prefixes increases. As far as the biggest contributor ARIN is concerned, the increase is very small. The highest increased in the last months can be identified for the APNIC RIR, which last year was still below RIPE and from beginning of this year has overcome it and became number two RIR in terms of /8 prefix utilization.
Figure presenting the total number of prefixes used 
shows the overall IPv4 /8 prefix statistics (including the reserved space for IANA) over time. As one can see the number is constantly increasing and it seems righ t now that eventually it will reach the total number of available IPv4 /8 prefixes. The author thinks that based on this chart the date of the exhaustion of the IPv4 address space could be estimated (one of the next steps for the author).

1. Approximate the total IPv4 prefix utilization to make an estimate of the possible date of the exhaustion of the IPv4 address space
2. Verify the number of assigned prefixes against the broadcasted ones (BGP) - hopefully statistics from http://bgp.potaroo.net could be used

You need to also show the "reserved" space (mulicast, type R, etc)
OdpowiedzUsuńThanks for the first comment ;)
OdpowiedzUsuńThe "reserved" space is presented on the pie chart (as IANA reserved - taken from http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.xml with status "RESERVED", multicast, private networks, class E etc.).
As far as the chart presenting the total number of /8 prefixes is concerned the reserved space should be there (especially for estimating the . Right now as I see the reservations are rather static -> I have updated the chart so that it includes the reserved address space. This has moved the curve a bit up... ;)
