A couple of years ago I used data from the kind folks at IPv4Auctions.com to plot trends in IPv4 market prices. They now publish that data,so I thought I’d see what prices are looking like. The same caveats from the previous post apply. Here’s a chart plotted from that data: I’ve added a couple of trendlines. The two purple extrapolations are […]

Recommended Reading on IPv6
A lot of people say that a lack of training is the biggest, or their biggest, roadblock to deploying IPv6. I’ve always said that a few hours of reading is all anyone needs. IPv6 is no more complicated than, say, OSPF, and arguably simpler than BGP. If you learned about IPv4 by working on networks […]
IPv4 Not Declared Historic
What happened at the sunset4 working group discussion at IETF95. You may remember my previous post about declaring IPv4 historic. IPv4 and IPv6 were specified in RFCs published by consensus at the IETF, the Internet Engineering Task Force. Changes required a new internet-draft to be written and discussed, and if it achieves consensus (usually after edits), it is […]
A Different Way to Predict Runout
For the past few months, I’ve been tracking Geoff Huston’s predictions for when ARIN will run out. The date changes as time passes, but interestingly, it’s changing at a constant rate: The x-axis is the date I recorded the predicted runout date. The y-axis is the date ARIN was predicted to run out of address space. When […]
Declaring IPv4 Historic
I’ve posted a new internet-draft, “IPv4 Declared Historic”. I thought I would describe the document, and why I chose to say what I said. First, the definition of historic: A specification that has been superseded by a more recent specification or is for any other reason considered to be obsolete is assigned to the “Historic” level. […]
Define “Runout”
This week, ARIN allocated another /12, bringing their inventory to less than half of a /8. Since they allocate based on 3-month need, this is “Last Call” for allocations. My friend @toreanderson pointed out that runout date varies based on the size block you need–something I’ve noted before, but haven’t detailed. So I built a spreadsheet. What if […]
Updated Look at IPv4 Market Transfers
I’ve been thinking about the rate of demand for IPv4 addresses. We can see demand on LACNIC and ARIN bringing them to the late phases of runout policy. Since APNIC and RIPE have entered their stingy final phases, the supply has nearly dried up. With no supply, the number of allocations made does not reflect […]
Lightning Poll: Three Questions on IPv6
A couple of weeks ago, I ran what I called a “Lightning Poll” at NANOG60, in which I asked three questions: In what year do you think IPv6 will be cheaper than IPv4 or dual-stack? In what year do you think IPv6 will offer better performance than IPv4? In what year will a significant number of […]
IPv6 is Faster
A couple of weeks ago, I ran a panel at NANOG60 about the IPv6 Performance Bonus. First, Geoff Huston showed some results from his experiments. He buys Google ads which run a bit of code, telling the browser to fetch a v6-only object and a v4-only object, and compares the times. He notes that in IPv4, a host will send […]
IPv6 for Consumers
Whenever a group of people talks about IPv6, eventually one of them says, “What we really need is a killer app, something that will get consumers to want IPv6.” I disagree with this. As a technology transition, if you’re waiting for consumers to ask, you’re doing it wrong. I’ve pointed out what I think are […]
