The 2012 IPv6 CPE Survey by Marco Hogewoning — last modified 17 Oct, 2016 09:00 AM

In response to a huge amount of demand, the RIPE NCC has conducted another survey on the level of IPv6 support for various vendor's Customer Premises Equipment (CPE). The questions in the 2012 focused around the most common access technologies. The results have been published using a simple colour coded matrix, listing which features are present, on the roadmap or not available. We've also developed a new interactive user interface so you're now able to filter the results and compare different models. This article will highlight some of the 2012 findings as well as some comparison to previous editions of the survey.

14th Saudi Arabian IPv6 Task Force Meeting by Marco Hogewoning — last modified 17 Oct, 2016 09:00 AM

The RIPE NCC recently participated in a meeting of the Saudi Arabian Task Force. A well-attended event, it included presentations and discussions about IPv6 deployment strategies, as well as presentations by operators reporting back on their successful IPv6 pilot projects and plans to roll out IPv6 in the first half of 2014.

Are We Ready to Switch Off IPv4? by Marco Hogewoning — last modified 17 Oct, 2016 08:56 AM

At the RIPE 67 meeting in Athens, Greece, the RIPE IPv6 Working Group ran a little experiment to test the feasibility of an IPv6-only network and to identify challenges in user experience. While the results were highly encouraging, they indicated that there is still work to be done before IPv4 can be switched off once and for all.

IPv6 to Secure Business Continuity by Marco Hogewoning — last modified 17 Oct, 2016 08:58 AM

Every few months somewhere somebody will tell you that the sky is falling and the end of the Internet is close. The reasons brought up vary through a broad spectrum from superior technology to the lack of capacity. To a large extent people in the industry have become immune to these messages, for they are either unrealistic or in cases where the threat was real, the Internet responded in its usual resilient ways, adopting to the changing environment. It is this remarkable flexibility and the constant search for optimisation that has made Internet seep into every little corner of our lives and businesses.

IPv6: Not a Product, a Building Block by Marco Hogewoning — last modified 17 Oct, 2016 08:57 AM

It seems that the biggest obstacle to a widespread deployment of IPv6 to date is the lack of a clear business case to recover the cost of such a deployment. The fundamental problem here is that the majority of market players still view IPv6 as a product, rather than what it really is: a building block to a new future.

EuroDIG 2015 Report by Corinne Cath by Marco Hogewoning — last modified 17 Oct, 2016 08:57 AM

For EuroDIG 2015, held in Sofia, Bulgaria on 3 and 4 June 2015, the RIPE NCC was pleased to be able to support the participation of Corinne Cath, who presented her work on human rights in the development of technical protocols at the recent RIPE 70 Cooperation Working Group session. Below is her impression of the conference.

Christmas Gift Idea: Some IPv6 Experience by Marco Hogewoning — last modified 17 Oct, 2016 08:57 AM

The holiday season is rapidly approaching and this year is coming to a close, another one done and another one that seen some great and wonderful and also unfortunately some sad moments. One of those key moments was the depletion of the IPv4 pool in the ARIN region, which for some probably means the sad realisation that their business models will hit a growth barrier.

LPWA: Things in Search of a Network by Marco Hogewoning — last modified 17 Oct, 2016 08:58 AM

Last week I had the opportunity to visit the LPWA IoT Networks Event in Amsterdam, a two-day conference dedicated to the use of low power wide area (LPWA) wireless networks that lie behind many Internet of Things (IoT) solutions that are entering the market.

Can You Make IPv6 Work Commercially? by Marco Hogewoning — last modified 01 May, 2019 03:56 PM

Large scale IPv6 deployments suggest that IPv6 is at least a technical success - the technology works. Now it's time to visit the other important question: does it work commercially? Does IPv6 really come with a positive business case? We are about to find out, if you help us... (for instance by filling in the poll next to the article)

For the Good of the Internet – of Things by Marco Hogewoning — last modified 17 Oct, 2016 08:56 AM

Sure, for some the Internet of Things is just an opportunity to make money. But what if it's also an opportunity to share our expertise - and in the process, make the world a better place?

50 Shades of NAT by Marco Hogewoning — last modified 16 Dec, 2016 03:15 PM

As a friend once told me, “there's a fine line between pleasure and pain.”* There's a vast body of literature to corroborate that story, not including the 100+ million copies of the book referred to in the title of this piece. But what does that have to do with Network Address Translation (NAT)? Could the reason we all love our NATs be that they're the network engineer’s guilty pleasure? How long before we permanently cross the threshold and are confronted with the painful reality of NAT's dark downsides?

A Slice of 5G by Marco Hogewoning — last modified 13 Feb, 2017 09:34 AM

The concept of a 5th generation of mobile networking is gaining traction – not only among policy makers but also in technical standardisation work.

"So long... and thanks for all the IPv6?" by Marco Hogewoning — last modified 05 Jun, 2018 04:22 PM

On 27 April 2005, the Dutch Ministry of Economic affairs, together with partners, established the Dutch IPv6 Task Force. Now, 13 years later, the decision has been made to dissolve the task force. We have come a long way and should celebrate its success, but the work is far from finished as far as helping people build capacity and deploy IPv6 is concerned.

A Review of Blockchain Applicability to Internet Number Resources by Marco Hogewoning — last modified 10 Nov, 2019 02:31 PM

Blockchain technology is receiving a lot of attention these days as a solution in numerous application domains. Triggered by research proposals and discussions in a variety of forums, we got together with a number of RIPE NCC employees to look at blockchain and its applicability to registration of Internet number resources. From our analysis we conclude that there are a number of issues that, at least for now, mean there is no benefit to using blockchain technology in the registry system.

ITU Plenipotentiary 2018: Through the Eyes of a Former Network Engineer by Marco Hogewoning — last modified 17 Sep, 2020 11:14 AM

The recently-ended Plenipotentiary Conference of the International Telecommunications Union (ITU) in Dubai was anything but a technical meeting, yet with the ITU’s mandate focused around telecommunications and ICTs, of course technological issues and challenges underpin many of the discussions. As the meeting resolves and instructs the different ITU Bureaux, especially the Telecommunications Standardisation Bureau (TSB), some of these instructions might impact technical decisions down the line. In this article, I’ll look at some of the conference’s output and try and assess the technology behind it. This is PP-18 from the perspective of a retired network engineer.

Routing to and from the Netherlands by Marco Hogewoning — last modified 25 Sep, 2019 01:10 PM

Following earlier publications, Radiocommunications Agency Netherlands asked if we could perform an analysis of the Dutch market – in particular, the routing arrangements between networks.

Do We Need a New IP? by Marco Hogewoning — last modified 22 Oct, 2020 11:15 AM

A number of recent publications have addressed Huawei’s proposal for a new internet-like architecture, called “New IP”, which aims to develop a set of protocols that could replace the current Internet. We believe that any evolution of the Internet should be left to the IETF, and we want to explain why.

Changing the Internet by Marco Hogewoning — last modified 24 Nov, 2020 02:11 PM

I recently had the opportunity to speak at a (virtual) event organised to celebrate the 25th birthday of the Moscow Internet Exchange. A great moment to look back at how the Internet has changed, and an even better one to discuss how best to handle changes yet to come. Here are the thoughts that formed the basis of my keynote.
