The prospect of exhaustion of the IPv4 address space is not a surprise. We've been anticipating this situation since at least 1990. But it's a "lumpy" form of exhaustion. It's not the case that the scarcity pressures for IP addresses are evidently to the same level in every part of the Internet. It's not the case that every single address is being used by an active device. A couple of decades ago we thought that an address utilisation ratio of 10% (where, for example, a block of 256 addresses would be used in a network with some 25 addressed devices) was a great achievement. more
The American Registry for Internet Numbers (ARIN) has launched a comic book series to further help raise awareness for the adoption of IPv6 and other matters dealt by the organization. The comic books, called "Team ARIN", are fictionalized views of the organization, its processes, and the whole concept of Internet governance. "Though our heroes are fictional, the issues they face are very real," says ARIN. more
At the outset I should say that here I would like to restrict my view to the transition from the IPv4 Internet to the IPv6 Internet, and, in particular, to examine the topic of the appropriate market structure that lies behind the dual stack transition strategy, and the manner in which the Internet can transition from the universal use of IPv4 as the underlying datagram protocol to the universal use of IPv6. more
What is the impact of IPv6 on telecommunications, VoIP, unified communications, etc? Why should telecom operators care about IPv6? What VoIP systems already support IPv6? What efforts are underway within organizations like the IETF and the SIP Forum to ensure that telecommunications can work over IPv6? more
A new research on native IPv6 traffic across six large providers in North America and Europe suggest that despite fifteen years of IPv6 standards development, vendor releases and advocacy, only a small fraction of the Internet has adopted IPv6. "The slow rate of IPv6 adoption stems from equal parts of technical/design hurdles, lack of economic incentives and general dearth of IPv6 content." more
Verizon has announced that starting June 30, 2017, it will stop issuing new Public Static IPv4 addresses due to a shortage of available addresses. more
I am writing this from the Satellite 2008 conference in Washington, D.C. As I make my way through the exhibits, I see many vendors advertising IP capabilities in their hardware products or network services. But when asked about IPv6 support, the common reply is a not so believable "it is on our roadmap" followed by a somewhat vague delivery date. Although IPv6 development has been slow across the board, it appears to be moving even more slowly in the satellite world... more
After a quick break to catch our breath (and read all those IPv6 Security Resources), it's now time to look at our tenth and final IPv6 Security Myth. In many ways this myth is the most important myth to bust. Let's take a look at why... Myth: Deploying IPv6 Makes My Network Less Secure... I can hear you asking "But what about all those security challenges we identified in the other myths?" more
I'm a network engineer, and like many engineers I often gravitate to the big projects; large networks with problems of scale and complexity in my case. However, I also consider myself a student of Occam's razor and often quote Antoine de Saint-Exupéry: "perfection is reached not when there is nothing left to add, but when there is nothing left to take away." In this spirit of "less is more" I have recently become intrigued by the problems appearing in home networking. more
There have been quite a number of recent articles about various IPv6 issues. Thus the question: how far along is the actual IPv6 deployment? This is a quick-and-dirty survey that focuses mainly on the content provider side. What domains were surveyed? Alexa offers country depended TopSites listings. Domains listed are frequently visited by users from that country, not necessarily hosted there... more
In a video interview conducted during the NSCS ONE conference, Paul Vixie CEO of Farsight Security further discusses the topic of his presentation titled: "Defective by Design -- How the Internet's Openness is Slowly Poisoning Us". more
A new report issued by the Number Resource Organization (NRO) has found that demand for both IPv4 and IPv6 address space is continuing to grow. The Internet Number Resource Status Report for the first quarter of 2010 is based on data collected by the five Regional Internet Registries (RIRs) that oversee the allocation of all Internet number resources, and outlines RIR allocation of IP address space (IPv4 and IPv6), as well as AS number assignments. In the report, the NRO notes that allocations of IPv4 addresses in Q1 have reduced the IANA free pool of IPv4 addresses to 8.5 percent. more
Researchers from Huazhong University of Science and Technology in China have started work on a project based on a distributed information retrieval system that promises to address future search engine scalability issues that are believed to be inevitable as the Internet continues to expand: "With the rapid increase of web pages, the coverage of search engines will become poorer and the update intervals will be much longer. If the current architecture of search engines is still in use, it will be an impossible mission to find the precise and comprehensive information in the future. This problem will be more serious when IPv6 technology is widely implemented in communication networks. The problem of 'Too much information means no information' may become a disaster with information explosion." more
In preparation for the World IPv6 Launch tomorrow, Vint Cerf, Chief Internet Evangelist at Google, and a founding father of the Internet, discusses the next version of the Internet, and why we need it. more
Last year the municipality of Gavle asked my company if we could help them load share the streaming pictures of the famous Christmas goat in Gävle. I accepted the invitation and set up a separate domain. My own interest in this was of course to track the usage of IPv6 and validation of DNSSEC from the visitors of the site. more
