One way or another the users of the Internet pay for the Internet. But this does not stop various players in the space jostling for relative advantage, claiming others should be paying more while they pay less. This tension is often reflected between carriage providers and content service providers when they try and figure out who should pay whom and how much. More... -------------------------------------------------------------------------------- THE POLITICS OF SUBMARINE CABLES IN THE PACIFIC JUNE 2022 Telecommunications infrastructure is not isolated from the world of politics, and its not just limited to pronoucments of who can provide 5G networks in various countries. The world of undersea cables is similarly being shaped by these same political tensions, and this is clearly evident in the western Pacific Ocean. More... -------------------------------------------------------------------------------- THE PATH TO RESOLVERLESS DNS MAY 2022 Using the DNS without directly using recursive resolvers seems like an approach that is totally alien to the DNS as we know it, so it might be useful to ask: How did we get to this point where a resolverless form of DNS name resolution makes some sense? And, to whom does it make sense? More... -------------------------------------------------------------------------------- ARE WE THERE YET? MAY 2022 This transition to IPv6 has been going on for 20 years now, and if there was any urgency that was instilled in the effort by the prospect of IPv4 address exhaustion then we’ve been living with exhaustion for a decade now. So perhaps it's time to ask the question: How much longer is this transition going to take? More... -------------------------------------------------------------------------------- USING LEOS AND GEOS APRIL 2022 Once you head off the main roads your Internet connectivity options are often pretty limited. However, things are improving, and in Australia you can use an Internet service based on a connection through a geostationary satellite connection or you could sign up for Starlink, a Low Earth Orbit service. Both services offer decent capacity, but there are some some other critical differences going on here. Let's look at these services using a custom test rig to put them through their paces. More... -------------------------------------------------------------------------------- HOP BY HOP APRIL 2022 It is a rare situation when you can create an outcome from two somewhat broken technologies where the outcome is not also broken. I’m referring to a recent effort to try and salvage something from the debacle that is IPv6 packet fragmentation support by taking another piece of operationally broken IPv6, namely Hop-by-Hop (HBH) extension headers, and trying to use that to solve the IPv6 Path Maximum Transfer Unit Discovery (PMTUD) problem. More... -------------------------------------------------------------------------------- AUSNOG '21 APRIL 2022 AUSNOG was held in April 2022 in Sydney over two days. Here are a few notes from presentations at the meeting that I found interesting. More... -------------------------------------------------------------------------------- IETF 113 - DNS TOPICS MARCH 2022 The IETF met in a hybrid format in March 2022. Here are my impressions from the DNS-related Working Group sessions during the week. More... -------------------------------------------------------------------------------- IETF 113 - IEPG MEETING MARCH 2022 The IEPG meets on the Sunday at the start of the IETF week. If there is a theme for the diverse collection of presentations here it is perhaps a focus on operational topics, but the particular selection of subjects in these sessions can be quite diverse. More... -------------------------------------------------------------------------------- REVOCATION MARCH 2022 A compromised private key should not be accepted. An attacker might use a compromised private key to impersonate a site, and this vulnerability needs to be prevented to ensure that users can use services over the network with trust in their integrity and security. The way to stop a compromised key from being accepted is to disseminate the information that the key is no longer trustable, and this is achieved by revoking the public key certificate. But we are having some problems in taking this theory and creating practical implementations of certificate revocation. More... -------------------------------------------------------------------------------- DNS-OARC 37 FEBRUARY 2022 There was a meeting of DNS Operations and Research group in February. These are my notes from the presentations that I found to be of interest. More... -------------------------------------------------------------------------------- ANOTHER YEAR OF THE TRANSITION TO IPV6 FEBRUARY 2022 Is there some end in sight for the protracted IPv6 transition? Are there some grounds to be a little more optimistic than we were a year ago? Or is this just an expression of our collective frustation about how long this transition is taking, and just wanting it to be over? More... -------------------------------------------------------------------------------- DNS4EU FEBRUARY 2022 The last few decades have not been a story of unqualified success for European technology enterprises. The European industrial giants of the old telephone world have found it to be extraordinarily difficult to translate their former dominant positions in the telco world into the Internet world. To be brutally frank, none of the current generation of major players in the digital environment are European. The concern is that if today’s technology world equates to the previous world of far-flung colonial empires then relative national wealth and prosperity appear to be linked to the ability to master, or preferably dominate, critical aspects of the sector. And in this respect Europe appears to have been left behind. More... -------------------------------------------------------------------------------- WHAT'S AN "ADDRESS"? FEBRUARY 2022 Currently, there are discussions in the IETF's Internet Area on the topic of architectural evolution of the Internet and its implications for the changing role of IP addresses, and I'd like to share some of my thoughts on this topic here. More... -------------------------------------------------------------------------------- IP ADDRESSING THROUGH 2021 JANUARY 2022 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. More... -------------------------------------------------------------------------------- BGP IN 2021 – BGP UPDATES JANUARY 2022 The scalability of BGP as the Internet's routing protocol is dependant on both the size of the routing space and the profile of dynamic updates within this space. This report looks at the profile of BGP updates across 2021 to assess whether the stability of the routing system, as measured by the level of BGP update activity, is changing. More... -------------------------------------------------------------------------------- BGP IN 2021 – THE BGP TABLE JANUARY 2022 At the start of each year, I have been reporting on the behaviour of the inter-domain routing system over the past 12 months, looking in some detail at some metrics from the routing system that can show the essential shape and behaviour of the underlying interconnection fabric of the Internet. More... -------------------------------------------------------------------------------- ICANN DNS RESOLVER SYMPOSIUM DECEMBER 2021 ICANN hosted a Resolver Operator Forum in mid-December, and the session had several interesting presentations that I would like to comment on here. More... -------------------------------------------------------------------------------- IPV4 ADDRESS MARKETS DECEMBER 2021 We have come down a long and tortuous path with respect to the treatment of Internet addresses. The debate continues over whether the formation of markets for IPv4 addresses was a positive step for the Internet, or a forced decision that was taken with extreme reluctance. Let’s scratch at this topic and look at the formation of this market in IP addresses and the dynamics behind it and then look at the future prospects for this market.
