…about the IP address of your default router (default gateway in IPv4-speak). It’s tough to argue against the fact that most IPv6 addresses are not much fun to type. Being four times longer than IPv4 addresses and expressed in hexadecimal means things can get ugly on the keyboard pretty quickly. For people in the IT…
I wrote this post several years ago. By writing it I was trying to get people to begin to think about how the size of the IPv6 address space, when combined with RFID technologies, was going to change everything about how they manage their lives. I wrote this way before NetFlix began streaming content, before…
The IANA (Internet Assigned Number Authority) distributes IPv6 address to RIR’s (Regional Internet Registry’s) around the world. At the moment there are five RIR’s and each of them is responsible for allocating IPv6 address space to ISP’s (Internet Service Providers) and, in some cases, End-User organizations. Once a block of addresses is allocated to an…
The IPv6 address space is huge. On paper each IPv6 subnet (/64) supports more than 18.4 quintillion hosts (millions, billions, trillions, quadrillions and then quintillions). It’s an amazingly large number. By every conceivable measure today we can’t contemplate a situation where anything but the tiniest portion of that address space will actually be utilized. Assuming…
“You hear that? That is the sound of inevitability…” – Agent Smith, The Matrix. You will migrate to IPv6. It is happening. You will not be able to resist. The IANA gave out the last IPv4 allocations on 2/1/2011. There are no more. As I write, the RIR’s will completely run out of IPv4 addresses…
