Disclosure: I am one of the world’s biggest fans of, and greatest advocates for, IPv6. In the words of rapper 50 Cent, “I love it like a fat kid loves cake.” Anyone I have ever been able to corner in a room knows this to be true. That being said… I just finished reading [yet…

I can sum it up with one sentence: IPv6 costs money, it does not make it. But the long ago the world received the commandment from the ether: Migrate! Migrate …and pay for it yourself with no immediately obvious capacity for a return on the investment. And we wonder why the migration is almost 20…
I’ll wager that 99% of people who read this from home are coming to me through an IPv4 NAT device that is only a few short steps from where they are sitting. NAT and IPv4, for reasons I understand yet still loathe, just go together these days. I’ll save my un-ending rant against NAT for…

I recently read a few articles from around the the Internet regarding the debate surrounding the use of /64 or /126 prefixes on P2P links. Here is a response I left on another site: “The idea of using /126′s is little more than scar tissue from our experience with IPv4. It is the application of…
Network Address Translation – A Black Mark on IPv4’s Name Why do people use Network Address Translation? Because they always have, that’s why. “That’s the way we’ve always done it” is one of the dumbest reasons we do things. It precludes continued thought and absolves us the responsibility to think about why we are doing…
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…
“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…
