Geoff Huston provides a bunch of statistics on the Internet address spaces. There are up to date graphs of the IPv4 and IPv6 address blocks, BGP routing tables and autonomous system numbers. Aside of these statistics, the site provides estimations when we will run out of addresses, based upon projected growth rates.
The experience of the Lawrence Berkeley Laboratory in tracking an intruder suggests that any operating system is insecure when obvious security rules are ignored.
