IP Addresses

Each device connected to the global Internet is assigned a unique Internet Protocol (IP) address, of the form: aaa.bbb.ccc.ddd, where each field is an octal number. For example, a printer, computer, or home DSL router might have the address: 192.155.202.198.

There are 4,294,967,296 unique addresses possible. There are 256 /8 blocks of addresses, where each /8 block corresponds to 16,777,216 unique IDs. At the beginning of 1983, no IP addresses had been assigned but in the near future the list of available addresses will be exhausted. Below  is a monthly time series of the total number of /8 blocks assigned from January 1983 (0.0 blocks, period 1) through August 2011 (220.85 blocks, period 345), in SMOOTHIE format.
