Among all the working groups that met at IETF 100 in Singapore was the first meeting of the DNS over HTTPs Working Group (DOH). I wrote on a related topic of DNS Privacy a little over a year ago, looking at the work at the time on the privacy-related topics…
The Mirai DDOS attack happened just over a year ago, on the 21st October 2016. The attack was certainly a major landmark in terms of the sorry history of “landmark” DDOS attacks in the Internet. It’s up there with the Morris Worm of 1988, Slammer of 2002, Sapphine/Slammer of 2009…
When writing this blog I am never sure who reads it and how they take it. Back in August I wrote up an examination of the behaviour of IPv6 and packet fragmentation with an observation relating to Google’s Public DNS Service. I used two example cases of queries for Google’s…
RIPE held its 75th meeting in Dubai in mid-October. As usual there was a diverse set of presentations covering a broad range of activities that are taking place on today’s Internet. The topics include issues relating to network operations, regulatory policies, peering and interconnection, communications practices within data centres, IPv6,…
The DNS OARC meetings are an instance of a meeting that concentrates on the single topic of the DNS, and in this case it delves as deep as anyone is prepared to go! It’s two days where too much DNS is barely enough! The hot topic of the meeting was…
For some years now (and it has definitely been two years, probably three and maybe longer) we have been working on a process of changing the cryptographic key that signs the Root Zone of the DNS. I wrote about this back in March 2016, describing both the role of this…
The IPv6 protocol introduced very few changes to its IPv4 predecessor. The major change was of course the expansion of the size of the IP source and destination address fields in the packet header from 32-bits to 128-bits. There were, however, some other changes that apparently were intended to subtly…
Interest in the DNS appears to come in waves. It’s quiet for a few years, then there is a furious burst of activity. We appear to be in the middle of a burst of activity, and there is probably enough material presented at the recent IETF meeting to cover the…
It’s hard to classify the IEPG meetings that occur at the start of the IETF week. Many years ago they had a role in allowing network operators to talk to other operators about what they were seeing and what they were thinking about. Those days are long since over, and…
OARC 26 was held in May in Madrid. Here are my impressions of the meeting, drawn from some presentations that I found to be of personal interest. All the presentations can be found at OARC’s web site.
