In the first part of this trilogy, I discussed the importance of automatically provisioned second generation DNS in connection with Software Defined Networking (SDN) and Software Defined Data Centre (SDDC). In the second post, I talked about IP addressing, private enterprise networks, and how DHCP does not meet the requirements of multitenant Infrastructure-as-a-Service (IaaS) cloud environments. I will now wrap up this trilogy by putting these two thesis into real-life context. more
In my previous post, I talked about the significance of DNS in connection with the Software Defined Data Center (SDDC) and Software Defined Networking. Although the second generation DNS provisioning model I outlined should have seemed straight-forward enough, in real life it is anything but. In my view, the real-world complications of a seemingly trivial issue are largely related to how the network industry approaches IP addressing. more
Here are the top ten most popular news, blogs, and industry updates featured on CircleID during 2012 based on the overall readership of the posts for the past 12 months. Congratulations to all the participants whose posts reached top readership and best wishes to the entire community for 2013. more
Well, 2012 is almost over, and we can now reflect on the major events that hit our industry this year. If I had to choose the top three trends from the past 12 months, they would have to be: 1. Over-the-top (OTT) services; 2. IPv6 deployments (finally!); 3. TR-069 adoption. Let's examine each of these in more detail. 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
The 85th meeting of the Internet Engineering Task Force (IETF) begins next week in Atlanta, Georgia, USA. Over 1000 engineers, maybe as many as 1400 or more, from all around the world will gather in various working groups to discuss and debate issues relating to the open standards that define the Internet's infrastructure. more
Couple of weeks ago I started a new initiative called "Names, Numbers and Beyond". I started this as I genuinely think we are facing big issues due to the uncontrolled and non-standard growth of the IP and Name space used today and tomorrow. To keep in control and make everything manageable, parcelling out IP address space and the use of tight naming standards/policies is necessary to make networks work better and make them achievable. 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
The RIPE NCC's membership grew steadily over the course of 2012. In Q3, the RIPE NCC received 417 requests to become a Local Internet Registry (LIR); the highest number we have seen so far. This surge in membership growth exceeds the previous record set 12 years ago during the dotcom bubble in 2000. One reason for the surge is probably the anticipation of the last /8 of IPv4 addresses. more
On Friday 14 September, 2012, the RIPE NCC, the Regional Internet Registry (RIR) for Europe, the Middle East and parts of Central Asia, distributed the last blocks of IPv4 address space from the available pool. more
The Internet Society Deploy360 Programme issues a call for speakers for a series of upcoming global ION Conferences. ISOC welcomes submissions from IPv6 and DNSSEC experts to speak at any of the following ION conferences. more
Reading Peter Olthoorn's book on Google (a link is found here), I ran into a passage on IP addresses. Where Google states that it does not see an IP address as privacy sensitive. An IP address could be used by more than one person, it claims. The Article 29 Working Party, the EU privacy commissioners, states that it is privacy sensitive as a unique identifier of a private person. It got me wondering whether it is this simple. Here is a blog post meant to give some food for thought and debate. I invite you to think about the question 'how private is an IP address'? more
As mentioned in Assigning 32-bit ASNs published one year ago, 16-bit Autonomous System Numbers (ASNs) are becoming a scarce resource just like 32-bit IP addresses. In 2007, the Internet Engineering Task Force (IETF) addressed this scarcity by developing a new format: 32-bit AS Numbers (RFC 4893), which increased the supply of ASNs to four billion. more
Some years ago a report was published that ranked countries by the level of penetration of broadband data services. You can find the current version of that report at the OECD web site. This ranking of national economies had an electrifying impact on this industry and upon public policies for broadband infrastructure in many countries. Perhaps this happened because there were some real surprises lurking in the numbers at the time. more
Contributing to international telecommunications standards, not in the IETF but in a more august and imposing body, the ITU-T, part of the United Nations, was quite an experience. Still called CCITT in those days, it was formal and solemn; everybody was part of and sat with their national delegation, countries were aligned in alphabetical order; nobody spoke out of turn, every word was simultaneously translated in the three official languages of the time and we wore suit and tie. more
