Tonight begins the third annual SIP Network Operators Conference (SIPNOC) in Herndon, Virginia, where technical and operations staff from service providers around the world with gather to share information and learn about the latest trends in IP communications services - and specifically those based on the Session Initiation Protocol (SIP). Produced by the nonprofit SIP Forum, SIPNOC is an educational event sharing best practices, deployment information and technology updates. Attendees range from many traditional telecom carriers to newer VoIP-focused service providers and application developers. more
There are still a number of countries who have Queen Elizabeth as their titular head of state. My country, Australia, is one of those countries. It's difficult to understand what exactly her role is these days in the context of Australian governmental matters, and I suspect even in the United Kingdom many folk share my constitutional uncertainty... In the United Kingdom every year the Queen reads a speech prepared by the government of the day, which details the legislative measures that are being proposed by the government for the coming year. Earlier this month the Queen's speech included the following statement in her speech. more
As the free pool of IPv4 addresses reaches its end, we looked at the evolution of the amount of unassigned IPv4 address space over time. By 'unassigned', we mean address space not yet allocated to a Local Internet Registry (LIR) or assigned to an end user. LIRs are typically Internet Service Providers or enterprises operating an IP network. See our findings in the graph below... more
In the previous graph and article published here two weeks ago, we showed that many ISPs in the RIPE NCC service region (Europe, the Middle East and parts of Central Asia) have not yet obtained IPv6 addresses from the RIPE NCC. Our latest graph demonstrates just how quickly this is changing. more
"Sky completes roll out of IPv6 becoming the first major UK Internet provider to future-proof its service for customers," announced the company in a press release on Tuesday. more
It is not often I go out to my driveway to pick up the Washington Post -- yes, I still enjoy reading a real physical paper, perhaps a sign of age -- and the headline is NOT about how the (insert DC sports team here) lost last night but is instead is about an IT technology. That technology is the Border Gateway Protocol (BGP), a major Internet protocol that has been around for more than a quarter century, before the Internet was commercialized and before most people even knew what the Internet was. more
The UK IGF was held on 1st July 2014 at St. Ermin's hotel, London, England. The Nominet Chair Baroness Rennie Fritchie gave the sponsor's welcoming remarks. She said "The IGF provides an opportunity for discussion, dialogue, divergent views, and encourages people to speak-up". The event had about 50 participants. The Minister for Culture, Communication and the Creative Industries Hon. Ed Vaizey, MP gave his keynote speech and fielded questions from participants. more
In Tony Li's article on path MTU discovery we see this text: "The next attempt to solve the MTU problem has been Packetization Layer Path MTU Discovery (PLPMTUD). Rather than depending on ICMP messaging, in this approach, the transport layer depends on packet loss to determine that the packet was too big for the network. Heuristics are used to differentiate between MTU problems and congestion. Obviously, this technique is only practical for protocols where the source can determine that there has been packet loss. Unidirectional, unacknowledged transfers, typically using UDP, would not be able to use this mechanism. To date, PLPMTUD hasn't demonstrated a significant improvement in the situation." Tony's article is (as usual) quite readable and useful, but my specific concern here is DNS... more
Yesterday Apple declared that as of June 1 all iOS apps submitted to the AppStore MUST support IPv6-only networking. Back at their June 2015 WWDC event, Apple announced that all iOS 9 applications must support IPv6 - the news this week is reinforcing that requirement... As Apple continues to point out, the vast majority of application developers will not need to do anything to support IPv6. more
The main reason for developing a new internet protocol was based on lack of address; however this was not the only reason. Unfortunately, many people think of IPv6 only as enormous address space, but there are a lot of other advantages, for example... authorizations and authentication function are implemented directly in the protocol and are mandatory... automatic configuration of network interfaces based on their physical address... protocol itself recognizes data streams which must be transmitted in real time, and the data must be processed with highest priority... more
During the last week of December, two US Government agencies released papers on IPv6. NIST released Special Publication 800-119, Guidelines for the Secure Deployment of IPv6. This comprehensive 188 page paper provides guidelines for federal agencies (and anyone else who might want to take advantage of it) to securely deploy IPv6. more
It seems everywhere I turn, there's someone throwing around statistics for how the Internet and broadband will drive economic growth, create jobs, end world hunger and bring world peace (ok, maybe not the later). Sure enough, government officials are buying into that rhetoric and extending it in initiatives like national broadband strategies, cybercrime and cybersecurity plans as well as e-governance strategies. more
The saga of the IPv6 transition continues to surprise us all. RFC 2460, the first complete effort at a specification of the IPv6 protocol, was published in December 1998, more than twenty years ago. The entire point of IPv6 was to specify a successor protocol to IPv4 due to the prospect of running out of IPv4 addresses. Yet we ran out of IPv4 addresses more than a decade ago. more
There is no doubt that the Internet continues to grow. While the sales volumes of the more traditional forms of personal computers has peaked at some 430 million units per year and sales of handheld smart devices has also peaked at some 1.9 billion units per year, the world of the Internet of Things continues to spiral upward. The installed base of these "things" is now at an astonishing 8.4 billion at the end of 2017. more
Recently, a couple of anti-spam (or at least email security related) bloggers have written some articles about IPv6 and the challenges that the email industry faces regarding it. John Levine, who has written numerous RFCs and a couple of books about spam fighting, writes the following in his article "A Politically Incorrect Guide to IPv6, part III". more
