Deploy360 Internet Exchange Points (IXPs) Internet of Things (IoT) IPv6

Promoting RIPE-690 @ Netnod

Our colleague Jan Žorž will be promoting RIPE-690 “Best Current Operational Practice: IPv6 prefix assignment for end-users – persistent vs non-persistent, and what size to choose” as the opening keynote at the forthcoming Netnod Meeting on 14-15 March 2018 in the Sheraton Hotel, Stockholm, Sweden.

RIPE-690 outlines best current operational practices for the assignment of IPv6 prefixes (i.e. a block of IPv6 addresses) for end-users, as making wrong choices when designing an IPv6 network will eventually have negative implications for deployment and require further effort such as renumbering when the network is already in operation. This was published in late 2017 after a year of intensive work by IPv6 experts around the world, supported by the Internet Society’s Deploy360 programme.

Netnod is a neutral, not-for-profit Internet infrastructure organisation based in Sweden that operates six Internet exchange points (IXPs) in five different cities where network operators can connect and exchange traffic.

There’s also several other interesting talks on the agenda, including trends in Internet-of-Things Distributed-Denial-of-Service botnets, prudent TLS, how to practically deploy IPv6 in the mass-market, how clouds are making new demands for connectivity and hyperconnected datacentres, and establishing research networks in Arctic environments, plus a panel session on the future of peering in the Nordic countries.

There’s still time to register, which is free provided you turn up!

Improving Technical Security Mutually Agreed Norms for Routing Security (MANRS) Technology

Taking MANRS on the Road Going North

Two weeks ago, we organized a panel discussion on the Mutually Agreed Norms for Routing Security (“MANRS”) document at NANOG65 in Montreal. It was wonderful to see that three MANRS participants – Tony Tauber (Comcast), Job Snijders (NTT), and Rob Hagens (Zayo) – were on the panel discussing some important aspects of MANRS and routing security in general. Andree Toonk from also participated, providing an overview of the security landscape.

Perhaps the most important questions were: (a) Why join MANRS? and (b) What difference can it make?

I think the takeaways from this discussion can be summarized in three bullet points:

  • Because security of the global routing system is a sum of all contributions
  • Because this is a way to visibly define and promote a new baseline in routing security
  • Because a community has gravity that can attract others, producing a network effect

Another, similar discussion happened again last week, this time in Northern Europe, in Stockholm during the Netnod meeting.

The title of my presentation, “How can we work together to improve security and resilience of the global routing system?” contained part of the answer that MANRS participants believe in: we can only improve the situation by working together. And the MANRS initiative itself offers a possible answer to the how.

Reflecting on an old well-known incident of YouTube prefix hijacking, one can observe that YouTube, by itself, could not protect its network from hijacking, but that Pakistan Telecom and PCCW could. What YouTube could have done is mitigate the attack – and that is what it did – but the damage had already been done. Another thing that a network can do is to help others to protect their networks. For instance, letting others know what announcements to expect by registering this information in an IRR, or RPKI.

The promise of MANRS is that it can help others to protect your network. But to make this happen, you should join, too.

There was strong support for the idea that implementing the actions identified in MANRS is a good way to go that can make routing more secure and reliable. There was less agreement that one should also join the MANRS initiative, though. Apart from traditional shyness (we are simply doing our job well), there are other factors, like perceived difficulties of convincing other people in the company of the benefits of this initiative.

Write us ( if you want to discuss this further, or simply share your doubts and concerns – that is very helpful, too!

And if you are ready and convinced – Gå med i MANRS idag!!

Deploy360 Events IETF

Discussing IETF at 2015 Spring NETNOD Meeting This Week

This Wednesday and Thursday, 11-12 March, I’ll be at the Spring NETNOD meeting in Stockholm, Sweden, to discuss our Operators And The IETF project and survey analysis.

We’ll have a panel discussion starting with the survey analysis and thoughts about first steps, followed by  discussion between panelists including current IETF participants, past participants, and non-participants. Let’s see what the outcome will be! I expect a heated discussion and hope for some good suggestions on how to improve the current situation.

Netnod meetings bring together operators, customers, friends, and partners of Netnod twice each year and feature programs that focus on technical talks that are interesting to network operators as well as to others in the Internet community at large.

If you happen to be at the 2015 Spring NETNOD meeting – come and find me in the crowd, I would be happy to chat about the Internet, the IETF, or any of our Deploy360 topics!

NETNOD Autumn 2014 Meeting In Stockholm – IPv6 Presentations

This year NETNOD Autumn meeting happened on 1st and 2nd October at Piperska Muren in Stockholm and brought together many excellent experts from the Internet community. I was invited to speak about two documents that are aimed at helping to remove some IPv6 deployment speed-bumps: RIPE-554 and “IPv6 troubleshooting for help desks“.

Compressing so much information about two documents in 30 minutes talk is very hard, especially because there is a lot to say about the content. I’ve been contemplating for a long time how to avoid walls of texts in presentation, but to no avail. If you put too little information on the slides, the context is lost for the people in the audience and especially for people that download the presentation later.

My talk was on the agenda on the first day before lunch and discussion afterward was encouraging. The community found both documents and efforts very valuable and useful. For those who could not attend, there is a set of slides available for download and maybe later there will be video recording of my talk.

NETNOD Autumn 2014 meeting turned out as a great event and I’m looking forward to next visit!
