From time to time the IETF seriously grapples with its role with respect to technology relating to users’ privacy. Should the IETF publish standard specifications of technologies that facilitate third party eavesdropping on communications or should it refrain from working on such technologies? Should the IETF take further steps and…
I guess that for me April has been DNS month, as here is another article on the Domain Name System. This time I would like to look at the efforts to expand the root zone service by enabling recursive resolvers. The root zone of the DNS has been the focal…
It seems that the previous article on DOH has generated some reaction, and also there is some further development that should be reported, all of which I’ll cover here. The previous article on the reactions to DOH at IETF 104 can be found at https://www.potaroo.net/ispcol/2019-04/angst.html. Default DOH First, with respect…
Many aspects of technology adoption in the Internet over time show simple “up and to the right” curves. There are many examples, so to pick a classic curve Google’s measurement of IPv6 use is a good example. What lies behind these curves is the theory that once a decision is…
Quick UDP Internet Connection (QUIC) is a network protocol initially developed and deployed by Google, and now being standardized in the Internet Engineering Task Force. In this article we’ll take a quick tour of QUIC, looking at what goals influenced its design, and what implications QUIC might have on the…
What part of “No!” doesn’t the DNS understand? One effective form of attack on the authoritative DNS server infrastructure, including the root servers, is the so-called random name attack. If you want to target the online availability of a particular domain name, then a random name attack will attempt to…
The first part of this report looked at the size of the routing table and looked at some projections of its growth for both IPv4 and IPv6. However, the scalability of BGP as the Internet’s routing protocol is not just dependant on the number of prefixes carried in the routing…
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. Back in around 1992 the IETF…
It has become either a tradition, or a habit, each January for me to report on the experience with the inter-domain routing system over the past year, looking in some detail at some metrics from the routing system that can show the essential shape and behaviour of the underlying interconnection…
Much has been written about the progress of the adoption of IPv6 over the years. I know I’ve been guilty of adding my writings into the pool, and this article is a further contribution to that pool of observations and measurements. In this case I want to look in some…
