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…
The stats.labs.apnic.net/ipv6 web has just grown a new feature: it can now account for the ASN contribution to an economies visible IPv6, when the ASN is not ‘resident’ in that economy. For most graphs, this doesn’t change much. But for some economies, its exposing the contribution of some significant ASN…
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…
A few weeks ago I wrote about Apple’s IPv6 announcements at the Apple Developers Conference. While I thought that in IPv6 terms Apple gets it, the story was not complete and there were a number of aspects of Apple’s systems that were not quite there with IPv6. So I gave…
For some years at APNIC Labs we have been conducting measurement experiments concerning the extent of use of IPv6 using a technique of embedding the measurements within the advertisement using Adobe Flash. The results of this measurement are fed into a set of measurement web resources at http://stats.labs.apnic.net/ipv6. The use…
In the coming weeks another Regional Internet Registry will reach into its inventory of available IPv4 addresses to hand out and it will find that there is nothing left. This is by no means a surprise, and the depletion of IPv4 addresses in the Internet could be seen as one…
It’s Apple’s Developers Conference time again, and in amongst the various announcements was week, in the “Platforms Status of the Union†presentation was the mention of IPv6. Sebastien Marineau, Apple’s VP of Core OS told the conference that as far as IPv4 addresses are concerned exhaustion “is finally hereâ€, noting…
In those circles where Internet prognostications abound and policy makers flock to hear grand visions of the future, we often hear about the boundless future represented by “The Internet of Thingsâ€. This phrase encompasses some decades of the computing industry’s transition from computers as esoteric piece of engineering affordable only…
At APNIC Labs we’ve been working on developing a new approach to navigating through some of our data sets the describe aspects of IPv6 deployment, the use of DNSSEC and some measurements relating to the current state of BGP.
The Organisation for Economic Co-operation and Development, the OECD, is a widely referenced and respected source of objective economic data and comparative studies of national economies and economic performance. The organization has a very impressive track record of high quality research and a justified reputation of excellence in its publications,…
