Network Address Translation has often been described as an unfortunate aberration in the evolution of the Internet, and one that will be expunged with the completion of the transition of IPv6. I think that this view, which appears to form part of today’s conventional wisdom about the Internet unnecessarily vilifies…
RIPE 74 was held in May in Budapest, and as usual it was a meeting that mixed a diverse set of conversations and topics into a very busy week. Here are my impressions of the meeting drawn from a number of presentations that I found to be of personal interest.…
Time for another annual roundup from the world of IP addresses. Let’s see what has changed in the past 12 months in addressing the Internet, and look at how IP address allocation information can inform us of the changing nature of the network itself. The process of exhausting the remaining…
It has often been claimed that IPv6 and the Internet of Things are strongly aligned, to the extent that claims are made they are mutually reliant. An Internet of Things needs the massively expanded protocol address space that only IPv6 can provide, while IPv6 needs to identify a compelling use…
This is the long version of the blog post. A shorter version is available here. There is a graph I’ve been pondering for some time that illustrates the topic I’d like to look at in this article. Figure 1 – Number of Routes announced…
The Border Gateway Protocol, or BGP, has been holding the Internet together, for more than two decades and nothing seems to be falling off the edge so far. As far as we can tell everyone can still see everyone else, assuming that they want to be seen, and the distributed…
Time for another annual roundup from the world of IP addresses. What happened in 2015 and what is likely to happen in 2016? This is an update to the reports prepared at the same time in previous years, so let’s see what has changed in the past 12 months in…
It has been said often enough that its easy to make predictions; the tough part is getting them right! And in trying to predict the manner that APNIC will exhaust its remaining supply of IPv4 addresses I’m pretty sure that I did not get it right in the most recent…
In 2010 the Asia Pacific Regional Address Policy community adopted a policy that permitted address holders in the region to transfer address registration records, enabling an aftermarket in IPv4 addresses to operate with the support of the APNIC registry function. While APNIC was still able to allocate addresses to meet…
It has been over 4 years since APNIC, the Regional Internet Registry for the Asia Pacific Region handed out its last “general use†allocation of IPv4 addresses. Since April 2011 APNIC has been restricted to handing out addresses from a “last chance†address pool, and has limited the amount of…
