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.
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.…
The IETF meetings are relatively packed events lasting over a week, and it’s just not possible to attend every session. Inevitably each attendee follows their own interests and participates in Working Group sessions that are relevant and interesting to them. I do much the same when I attend IETF meetings.…
Few parts of the Domain Name System are filled with such levels of mythology as its root server system. Here I’d like to try and explain what it is all about and ask the question whether the system we have is still adequate, or if it’s time to think about…
There is a frequently quoted adage in communications that goes along the lines of “Good, Fast, Cheap: pick any two!” It may well be applied to many other forms of service design and delivery, but the basic idea is that high quality, high speed services are costly to obtain, and…
In November I wrote about some simple tests that I had undertaken on the DNS Root nameservers. The tests looked at the way the various servers responded when they presented a UDP DNS response that was larger than 1,280 octets. I awarded each of the name servers up to five…
The process of rolling the DNS Root’s Key Signing Key of the DNS has now started. During this process there will be a period where the root zone servers’ response to a DNS query for the DNSKEY resource record of the root zone will grow from the current value of…
The recent attacks on the DNS infrastructure operated by DYN in October 2016 have generated a lot of comment in recent days. Indeed, it’s not often that the DNS itself has been prominent in the mainstream of news commentary, and in some ways this DNS DDOS prominence is for all…
