How are you Deploying IPv6? Take this Survey
Jordi Palet Martinez — 31 May 2016

After 15 years conducting training on IPv6 in over 110 countries, I’ve been asked all sorts of questions. “How do I use my IPv6 addressing space?” “What prefix size should I provide to customers?” Although I have answers to these and many other best practice related questions, the one question, which I have not been able to answer to the best of my ability, is “What is the approach of other ISPs?”. So I decided to find out.

Fragmenting IPv6
Geoff Huston — 19 May 2016

The design of IPv6 represented a relatively conservative evolutionary step of the Internet protocol. Mostly, it's just IPv4 with significantly larger address fields. Mostly, but not completely, as there were some changes. IPv6 changed the boot process to use auto-configuration and multicast to perform functions that were performed by ARP and DHCP in IPv4. IPv6 added a 20-bit Flow Identifier to the packet header. IPv6 replaced IP header options with an optional chain of extension headers. IPv6 also changed the behaviour of packet fragmentation. Which is what we will look at here.

The Internet for Things
The Internet for Things
Mirjam Kühne — 10 May 2016

Please read this guest post by Byron Ellacott, Senior Software Architect at APNIC: The Internet of Things without the Internet is just things, and we’ve had things since the first caveman used a pointy stick to draw on a wall. What then does the Internet bring to things to justify a capital T?

RIPE Atlas Update: DNSMON Code Available, LatencyMON Comparisons, New Credit Sharing and More
RIPE Atlas Update: DNSMON Code Available, LatencyMON Comparisons, New Credit Sharing and More
Suzanne Taylor Muzzin — 30 Mar 2016

In the past few months, we've added some new features and functionality to RIPE Atlas, including making the DNSMON code available on GitHub for personal use, displaying IPv4 vs IPv6 comparisons in LatencyMON, new credit sharing options, and new limits on probes per measurement and results per day. Learn more about the latest updates - and don't forget to tell us what you think.

10,000 LIRs with IPv6 Resources
10,000 LIRs with IPv6 Resources
Nathalie Nathalie — 29 Feb 2016

This week, the RIPE NCC saw a milestone as the 10,000th Local Internet Registry (LIR) received IPv6 addresses. The first block of IPv6 addresses was allocated from IANA to the RIPE NCC in 1999, so we have been distributing IPv6 addresses for 17 years. In those years we have seen interesting policy developments, making it easier for LIRs to obtain enough IPv6 to satisfy their needs. In this article we track the policy developments that have made it progressively easier for LIRs to get the IPv6 they need.

On the Internet, Everyone is Connected to Everyone Else. Right?
On the Internet, Everyone is Connected to Everyone Else. Right?
Geoff Huston — 22 Feb 2016

We tend to make a number of assumptions about the Internet, and sometimes these assumptions don’t always stand up to critical analysis. We were perhaps ‘trained’ by the claims of the telephone service to believe that these communications networks supported a model of universal connectivity. Any telephone handset could establish a call with any other telephone handset was the underlying model of a ubiquitous telephone service, and we’ve carried that assumption into our perception of the Internet. On the Internet anyone can communicate with anyone else – right?

Evaluating IPv4 and IPv6 Packet Fragmentation
Evaluating IPv4 and IPv6 Packet Fragmentation
Geoff Huston — 29 Jan 2016

One of the more difficult design exercises in packet-switched network architectures is that of the design of packet fragmentation. In this article, I’d like to examine IP packet fragmentation in detail and look at the design choices made by IP version 4, and then compare that with the design choices made by IP version 6.

Christmas Gift Idea: Some IPv6 Experience
Christmas Gift Idea: Some IPv6 Experience
Marco Hogewoning — 14 Dec 2015

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.

Examining IPv6 Performance
Examining IPv6 Performance
Geoff Huston — 26 Nov 2015

Every so often I hear the claim that some service or other does not support IPv6 not because of some technical issue, or some cost or business issue, but simply because the service operator is of the view that IPv6 offers an inferior level service as compared to IPv4, and by offering the service over IPv6 they would be exposing their clients to an inferior level of performance of the service. But is this really the case? Is IPv6 an inferior cousin of IPv4 in terms of service performance?

Measuring Countries and IXPs with RIPE Atlas
Measuring Countries and IXPs with RIPE Atlas
Emile Aben — 23 Mar 2015

We've been working with various Internet Exchange Points (IXPs) over the last few months to see how RIPE Atlas active measurements can provide insight into how they are keeping local traffic local. This could help improve performance and efficiency for IXPs and their members. To explore this, we've created a set of Python scripts to analyse Internet traffic paths between RIPE Atlas probes in a given country and try to identify whether they traverse IXPs.
