An increasing number of countries are passing laws that facilitate the mass surveillance of their citizens. In response, governments and citizens are increasingly paying attention to the countries that their Internet traffic traverses. In some cases, countries are taking extreme steps, such as building new IXPs and encouraging local interconnection to keep local traffic local. We find that although many of these efforts are extensive, they are often futile, due to the inherent lack of hosting and route diversity for many popular sites. We investigate how the use of overlay network relays and the DNS open resolver infrastructure can prevent traffic from traversing certain jurisdictions.
One of the Internet’s key features is that it keeps networking functions separate from the applications and services that use these functions. However, network operators and especially Internet service providers appear to be becoming more content aware. Networking is becoming more intertwined with content. This might have implications for tomorrow’s Internet.
The RIPE NCC is building relationships with external organisations and documenting the relationships we already have in order to broaden the support for and understanding of RIPE, the RIPE NCC and the global registry system.
This article is intended to make RIPE Atlas users aware of ethical issues that could arise when using RIPE Atlas. We do not intend to propose any new formal processes or procedures to address the relevant ethical issues, but we do want to encourage members of the RIPE Atlas community to consider the ethical impact of their behaviour when using RIPE Atlas.
The fourth RIPE NCC Hackathon was as fun and productive as the previous three, with even more supporting organisations and participants. This short article aims to express our gratitude to everyone involved and to give a summary of our experiences, while several projects will be described in more detail in the follow-up articles.
Geoff Huston discusses the possible demise of transit services and the rise of content networking.
The recent attacks on the DNS infrastructure operated by Dyn have generated a lot of comment in recent days. Indeed, it’s not often that the DNS itself has been prominent in the mainstream of news commentary and, in some ways, this DNS DDoS prominence is for all the wrong reasons! I’d like to speculate a bit on what this attack means for the DNS and what we could do to mitigate the recurrence of such attacks.
This is the final post in a series on Network Address Translation (NAT), provided by Mark Smith. In this post, Mark discusses the fundamental constraints of NAT and addresses some FAQs about IPv6 without NAT.
This is the second post in a series on NATs contributed by Mark Smith, based on a presentation given at AusNOG 2016. In the first post, Mark discussed Network Critical Success Factors (NCSFs). In this post, he is going into details about the trouble with Network Address Translation (NAT).
This is a guest post by Mark Smith, based on a presentation he gave at the AusNOG 2016 conference on this topic. This is the first post of three, and in this article Mark will discuss the concept of Network Critical Success Factors (NCSFs) before getting into ‘the trouble’.
"Measuring the Internet" has become an increasingly essential practice in many different areas. The fact that we are living in an era where Cloud services and CDNs are becoming more accessible and worldwide presence is within hand's reach for practically anybody, making informed decisions through measurements can both save money and help to find optimal performance.
We used a number of RIPE NCC tools and data sets to take a quick look at the recent DDoS attack on Dyn’s infrastructure. We wanted to see if this could be found in the data produced by the RIPE Atlas community.
Maybe surprisingly, there is quite an overlap between the RIPE community and the hackers community. Visiting a local hackerspace has been a tradition for more than five years: during RIPE Meetings, network operators groups, IXP meetings and other technical events. This is a nostalgic look back to the history of these encounters, and an invitation to join us for future explorations.
The exhortations about the Internet’s prolonged transition to version 6 of the Internet Protocol continue, although after some two decades the intensity of the rhetoric has faded and, possibly surprisingly, it has been replaced by action in some notable parts of the Internet. But how do we know there is action? How can we tell whether, and where, IPv6 is being deployed in today’s Internet?
On 17 October 2016, a website hosted by the French Ministry of the Interior went offline when a large number of customers of the Internet service provider, Orange, were redirected to the site. The problem occurred after Google, Wikipedia and cloud provider OVH were mistakenly placed on a terrorism block list.
Please read this guest post by Tony Scheid about fighting Distributed Denial of Service (DDoS) attacks during the Olympics in Rio de Janeiro.
"Non-public measurements" is a feature of RIPE Atlas that allows users to use the infrastructure to measure things while not sharing those results with the public. Is that still a useful feature? Should it exist in the future? Please take the polls.
Two years ago we released the RIPE NCC Academy - an online training service. Now we've launched the third training module: the Local Internet Registry (LIR) course.
RIPE Atlas lets you make customised measurements from thousands of probes around the world. These measurements cost credits, which users usually earn by hosting or sponsoring RIPE Atlas probes - or you may have just been given a million RIPE Atlas credits as a member of one of the Regional Internet Registries. Find out how you can best spend your credits to check your services' connectivity and troubleshoot potential issues.
It was about one year ago that the RIPE community reached consensus on a policy proposal that introduced additional criteria for initial IPv6 allocations. We thought it was time to look back at the origins of this proposal and see how the change has worked out since.
