Below are some statistics extracted from the routing table of rrc03.ripe.net.
These analyses are based on one routing table snapshot per month

Growth of IPv4 routing table size

Growth of the IPv4 routing table since 2000


Number of Autonomous Systems in IPv4 routing table

This graph represents the growth of the number of Autonomous Systems in IPv4 routing table.
Note that this is growing at a fairly constant rate, closely matching a linear growth


Growth of IPv6 routing table size

Growth of the IPv6 routing table since December 2002.
December 2002 is the start of this IPv6 data set. IPv6 did start earlier then this date
In interesting point in this graph is June 2006 (6-6-2006) the end of 6BONE. At that point the number of prefixes in the IPv6 routing table dropped with ~100 / ~150 prefixes.


Number of Autonomous Systems in IPv6 routing table

This graph represents the growth of the number of Autonomous Systems in IPv6 routing table.
In this graph you'll see Origin AS vs. the Total amount of AS's in the IPv6 table


Number of 4 bytes Autonomous Systems in routing table

The growth of 4 byte Autonomous Systems in the routing tabledivided by IPv4, IPv6
Looking at this date, 4byte ASN support in the RIS servers apparently started at April 2007.
