The number of available IPv4 addresses is rapidly shrinking down to zero. IPv4, which uses an address space of 32-bits (four bytes, as in 255.255.255.255), is expected to be exhausted by Wednesday afternoon. Not to worry though, as IPv6, which has a whopping 128-bits of address space (8 x 16-bit words), is already deployed and is expected to be tenable for considerably longer. Unless, of course, the Internet of Things happens, in which case we’ll run out by Christmas*.
Anyway, if you’d like to watch the numbers count down to zero, here are some IPv4 countdown clocks (none of which appear synchronized to each other):
Hurricane Electric’s Week-Day-Hour-Minute-Second Dial Clock (pictured above).
inetcore’s IPv4 Exhaustion Counter – I like this one because it shows you the realtime IP availability number.
British Telecom’s IPv4 Countdown.
or you can follow @IPv4Countdown on twitter.
