The Future of Home Networking: A Problem Statement

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-ExupĂ©ry: "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»

IETF 85 Begins Next Week In Atlanta - Here Is How To Follow Along

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»

Names, Numbers and Beyond…

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»

Akamai Reports 460 Times Increase in IPv6 Requests Over Its Platform Since Last Year

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»

New LIRs and Their IPv6 RIPEness

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»

RIPE NCC Distributed Last IPv4 Address Space from the Available Pool

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»

Internet Society ION Conferences: Call for Speakers - IPv6 and DNSSEC Experts

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»

IP Addresses and Privacy Sensitive Data - A Level Playing Field Needed

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»

Update on Assigning 32-bit ASNs

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»

Measuring IPv6 - Country by Country

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»

IPv6 and IP Convergence: Are International Treaties About to Govern the Internet?

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»

Measurement Results from World IPv6 Launch

As announced on RIPE Labs we monitored the behaviour of a number of networks that participated in the World IPv6 Launch on 6 June 2012. For that, we looked at the full list of participating organisations as shown on the ISOC website and chose 50 websites from that list. We looked at 'interesting' sites and at geographic distribution. We also tried to find a good mix of networks that had IPv6 switched on already and those that didn't have IPv6 deployed at the time they registered on the ISOC web site. more»

Do We Need An IPv6 Flag Day?

In recent interviews about World IPv6 Launch I've been asked by several different people whether or not I think there needs to be some kind of a "Flag Day" on which the world all together switches from Internet Protocol version 4 (IPv4) to the version 6 (IPv6). I don't think a flag day is needed. World IPv6 Launch is just the right thing. It's worth looking at some previous flag-type days to get a better sense of why. more»

World IPv6 Launch: Now What?

World IPv6 Launch kicked off 6 June 2012 at 00:00 UTC. On this day, multitudes of website operators, network operators and home router vendors from all over the world have joined thousands of companies and millions of websites in permanently enabling the next generation Internet. They have done this by turning IPv6 support on by default in (at least some of) their products and services. This is a major milestone in the history of the Internet. more»

Vint Cerf: The Launch of a New Larger Internet

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»
