A Look Back at the World of IP Addressing in 2017: What Changed and What to Expect

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

Digital Economy + Sharing Economy = Networked Economy

A great deal of discussion is taking place about topics such as the digital economy, sharing economy and networked economy. Obviously these are concepts rather than being well-defined, but they are being used by the various players in the market to argue for or against certain developments. For example, in some of the broadband debates around the world, the digital economy is the key reason why national broadband infrastructure gets developed. more

Russia Appears to Have Begun Providing an Internet Connection to North Korea

Network experts monitoring North Korea have detected activation of a new internet path out of North Korea. Doug Madory, Director of Internet Analysis at Dyn, along with North Korea expert Martyn Williams, report that at 09:07:51 UTC on 1 October 2017, the country's single internet provider, Star JV (AS131269), gained a new connection to the global internet through Russian fixed-line provider Transtelecom (AS20485), often referred to as TTK. more

Business Case for IPv6 - Part 1

When discussing IPv6, it is easy to forget that we are ultimately talking about an enhanced version of an existing network protocol. Sure, it brings about a number of technical advantages. But when viewed in isolation - without a business case - there really are not that many drivers that would place IPv6 on the agenda of the top decision makers looking after budgets. For IPv6 to gain serious momentum, this has to be changed. more

Addressing 2013 - That Was the Year That Was

Time for another annual roundup from the world of IP addresses. What happened in 2013 and what is likely to happen in 2014? This is an update to the reports prepared at the same time in previous years, so let's see what has changed in the past 12 months in addressing the Internet, and look at how IP address allocation information can inform us of the changing nature of the network itself. more

What Is the World Community Grid?

Innovation is one of those words that is a bit hard to internalize. Merriam-Webster says innovation is the introduction of something new or a new idea, method, or device. That would be a narrow definition, perhaps even obsolete. Innovation is much more than invention or introducing new technology. Some would say that innovation is more of a state of mind, an attitude. One thing is for sure: innovation is happening more quickly; it is more open and more collaborative. more

The Importance of IP Resource Planning in Government ICT Strategic Plans

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 IETF’s *Other* Diversity Challenge

The Internet Engineering Task Force (IETF) is the standards body for the Internet. It is the organization that publishes and maintains the standards describing the Internet Protocol (IP -- versions 4 and 6), and all directly related and supporting protocols, such as TCP, UDP, DNS (and DNSSEC), BGP, DHCP, NDP, the list goes on, and on... But how do they do that? How does the IETF produce documents, and ensure that they are high quality, relevant, and influential? more

The End of HFC and FttN Networks is Approaching

In the global telecoms industry, it looks as though 2013 will be remembered as the year when construction of new greenfield HFC networks came to a halt. Of course, there will still be upgrades to existing networks but the cost of fibre deployment -- linked to its much lower operational cost -- is now convincing cablecos and telcos alike to build new fibre networks wherever possible. This is not necessarily directly driven by customer demand, but by network costs and network efficiencies. more

One Year Later: Who’s Doing What With IPv6?

One year on from the World IPv6 Launch in June 2012, we wanted to see how much progress has been made towards the goal of global IPv6 deployment. Both APNIC and Google are carrying out measurements at the end user level, which show that around 1.29% (APNIC) and 1.48% (Google) of end users are capable of accessing the IPv6 Internet. Measurements taken from this time last year show 0.49% (APNIC) and 0.72% (Google), which means the amount of IPv6-enabled end users has more than doubled in the past 12 months. more

Open DNS Resolvers - Coming to an IP Address Near You!

Three vectors were exploited in the recent DDoS attack against Spamhaus: 1) Amplification of DNS queries through the use of DNSSEC signed data; 2) Spoofed source addresses due to lack of ingress filtering (BCP-38) on originating networks; 3) Utilisation of multiple open DNS resolvers While. 1) is unavoidable simply due to the additional data that DNSSEC produces, and 2) "should" be practised as part of any provider's network configuration, it is 3) that requires "you and I" ensure that systems are adequately configured.  more

IPv6: Childhood’s End?

A few weeks ago, when I was lurking around IPv6, I found that my own www.ipv6.tk was my first ever IPv6 domain. A "whois" on the domain says that it was registered in 2005, but something told me that I actually started this earlier. ?I therefore logged in at www.nic.tk and could see that my first feeling was correct; the first invoice for ipv6.tk was actually paid in the year of 2002. Here are some of the key things that I have experienced and learned over my first ten years. more

The Top 3 Emerging Threats on the Internet

Last week at RSA, Bruce Schneier gave a talk on the top 3 emerging threats on the Internet. Whereas we in the security field usually talk about spam, malware and cyber crime, he talked about three meta-trends that all have the potential to be more dangerous than the cybercriminals. Here are my notes. more

SIP Trunking: Common Pitfalls and Quick Fixes

With companies shifting away from on-premises and "traditional" telecom networks to Internet-based protocols - such as Voice Over IP (oIP) - the market for critical communications infrastructure - most notably SIP trunking - is on the rise; not only multiple failover sites but cloud-based SIP-as-a-service solutions are now popular options. However, there's a caveat: problems unique to SIP systems that can cause IT headaches if you're not prepared. Here are three of the most common. more

The Internet and OpenStand: The Internet Didn’t Happen by Accident

On the World Standards Day of 2013 it seems appropriate to recognize that on the Internet and throughout the Web, nothing goes anywhere without standards. These technical standards - communication protocols, data exchange formats, and interfaces - allow different computers and networks to talk to each other. They are the lifeblood around the world for multibillion dollar industries that didn't exist 20 years ago. They are born of a collaborative, open process that prides itself on technical expertise and measures success by the depth and breadth of their acceptance across a hodgepodge of vastly different technologies all interconnected to what we euphemistically call "the Global Internet." more
