With IPv4 address exhaustion upon us, it appears that the going market rate for IPv4 addresses is now $12/address. Over at the Register, Kevin Murphy reports on a bankruptcy filing from Borders seeking to sell a /16 block of to healthcare software vendor Cerner for a total of $786,432. At $12 per IPv4 address, this sets a new public record given that the previous high was Microsoft's acquisition of a block of Nortel IPv4 addresses... more
On the 6th June 2012 we held the World IPv6 Launch Day. Unlike the IPv6 event of the previous year, World IPv6 Day, where the aim was to switch on IPv6 on as many major online services as possible, the 2012 program was somewhat different. This time the effort was intended to encourage service providers to switch on IPv6 and leave it on. What has happened since then? Have we switched it on and left it on? What has changed in the world of IPv6 over the past 12 months? Who's been doing all the work? more
I spend most of my time teaching engineers in different countries how to plan and deploy IPv6 networks. Over the last two years, I have been speaking more and more to non-engineers. These are either technology executives who sense that they need to do something about this "IPv6" thing, or government IT leaders who want to understand what the problem is and more importantly, what they could do. The most impactful part of these these exchanges is when I get these managers to understand the implications of IPv4 address exhaustion to their organisations. more
In its latest State of the Internet report, Akamai has highlighted industry numbers showing imminent global exhaustion of IPv4 addresses. Report has also identifies 460 times increase in IPv6 requests over Akamai's platform from June 2011 – June 2012. A fair amount of the IPv6 request growth is attributed to the "World IPv6 Launch" event held on Jun 6, 2012 organized by the Internet Society. more
Network Address Translation has often been described as an unfortunate aberration in the evolution of the Internet, and one that will be expunged with the completion of the transition of IPv6. I think that this view, which appears to form part of today's conventional wisdom about the Internet unnecessarily vilifies NATs. In my opinion, NATs are far from being an aberration, and instead, I see them as an informative step in the evolution of the Internet, particularly as they relate to possibilities in the evolution of name-based networking. Here's why. more
Controversies over ICANN led to the creation of the Working Group on Internet Governance, but so far there have been few specific proposals for change. The Internet Governance Project has entered that breach with a new policy paper: "What to Do About ICANN: A Proposal for Structural Reform." The proposal, by Hans Klein and myself, proposes three clean, clear but probably controversial solutions to the criticisms that have been made of ICANN. more
The following is a report by Susan Crawford at the ICANN meeting in Cape Town where a workshop was held yesterday for increasing awareness and understanding of United Nation's World Summit on the Information Society (WSIS) and issues that directly impact ICANN. "WSIS" is defined as a process in which governments intend to address a broad range of international legal, regulatory, economic, and policy issues related to the Internet. Some governments have proposed that an intergovernmental organization be responsible for "Internet governance," a phrase that remains undefined and some consider to include and/or mean the administration and coordination of the domain name system (DNS). more
Although IPv6 DDoS attacks are not yet a common occurrence, there are indications that malicious actors have started testing and researching IPv6 based DDoS attack methods. more
The OECD held a "high-level" meeting in June 2011 that was intended to build upon the OECD Ministerial on The Future of the Internet Economy held in Seoul, Korea in June 2008. I was invited to attend this meeting as part of the delegation from the Internet Technical Advisory Committee (ITAC), and here I'd like to share my impressions of this meeting. This 2 day meeting, "The Internet Economy: Generating Innovation and Growth", had the objective of exploring a number of current issues in the public policy space... more
I'm sure this is something that's been raked over before, but I don't see a common understanding of what 'Net Neutrality' actually is. Despite many of the Internetorati demanding it by law. There appear to be several different camps, which you could paint as "bottom of IP", "middle" and "top". The bottomistas would see enforced Internet Protocol itself as a premature optimisation and violation of the end-to-end principle. Unhappy that you only get IPv4 or IPv6? Still grumpy that you only have IPv4 and not even IPv6? Really miserable that your VoIP packets are staggering under the poisonous load of IPv6 headers? You're a bottomista. more
Internet Protocol addresses fill two unique roles. They are both identifiers and locators. They both tell us which interface is which (identity) and tell us how to find that interface (location), through routing. In the last myth, about network scanning, we focused mainly on threats to IPv6 addresses as locators. That is, how to locate IPv6 nodes for exploitation. Today's myth also deals with IPv6 addresses as identifiers. more
Last month's column looked at the exhaustion of the IPv4 unallocated address pool and the state of preparedness in the Internet to grapple with this issue... There has been a considerable volume of discussion in various IPv6 and address policy forums across the world about how we should respond to this situation in terms of development of address distribution policies. Is it possible to devise address management policies that might both lessen some of the more harmful potential impacts of this forthcoming hiatus in IPv4 address supply, and also provide some impetus to industry to move in the originally intended direction to transition into an IPv6 network? more
IPv6 took a significant step forward this week with ICANN's decision to officially add the next generation protocol to its root server systems. The shift to IPv6 is perhaps the largest and most significant change to the structure of the Internet in decades - ICANN's move a signal that the revolution has officially begun. more
The active measurements the RIPE NCC carried out on World IPv6 Day on 8 June 2011 included ICMP (Internet Control Message Protocol) and ICMP6 (ICMP for IPv6) measurements from our vantage points to selected hostnames of World IPv6 Day participants and other dual-stacked parties. We used these measurements to determine the performance of IPv4 versus IPv6 connections. more
It's Apple's Developers Conference time again, and in amongst the various announcements was week, in the "Platforms Status of the Union" presentation was the mention of Apples support of IPv6. Sebastien Marineau, Apple's VP of Core OS told the conference that as far as IPv4 addresses are concerned, exhaustion "is finally here", noting that this already started in 2011 in the Asia Pacific while in North America IPv4 address exhaustion is imminent. Sebastien noted that it's really important to support IPv6 in devices and applications these days... more
