IPcalypse Now — Less Than 4 days Until IPv4 Exhaustion
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):
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

Time for a good cleanup! The ICANN/IANA must have a lot of unused IPv4 address ranges laying around that are not being used. I know for a fact that the WHOIS database still holds a record for a class-C address range of a company I worked for that hasn’t been used (or been paid for) for probably 12 or 14 years. There must be many such abandoned addresses and I wonder if a market is going to pop up to sell those to the highest bidder…
According to Wikipedia the surface of the earth is 510 km² or 510e12 m² wide. Distribute 2^128 IP Adresses and you’ll get 6,7e23 IP-Adresses/m². So who cares if every fucking “Thing” had his own IP? Nobody.
Too bad IPv6 only has 32bits of globally routable networks (the only things that count). So not that much bigger than IPv4 with 32bits of globally routable addresses when you assume an average of 50 hosts/network…
Stupid design-by-commitee protocol.
“is already deployed”
Good luck actually passing ipv6 traffic on the majority of networks right now.
And just because Arin runs out does not mean that the ISPs with the blocks don’t have reserves. A lot of the larger providers will be able to resubnet for a while.
