NANOG held its 68th meeting in Dallas in October. Here’s what I found memorable and/or noteworthy from this meeting. The meeting opened with Scott Bradner and a history of the IANA. Given that the arrangements with the US Government exercising some level of oversight on the IANA function lapsed on…
October 2016 marks a milestone in the story of the Internet. At the start of the month the United States Government let its residual oversight arrangements with ICANN (the Internet Corporation for Assigned Names and Numbers) over the operation of the Internet Assigned Numbers Authority (IANA) lapse. No single government…
DNS OARC is the place to share research, experiences and data primarily concerned with the operation of the DNS in the Internet. Some highlights for me of the most recent meeting, held in October 2016 in Dallas, were: DNS DDOS attacks: This presentation was about using an authoritative server exhaustion…
The exhortations about the Internet’s prolonged transition to version 6 of the Internet Protocol continue, although after some two decades the intensity of the rhetoric has faded and, possibly surprisingly, it has been replaced by action in some notable parts of the Internet. But how do we know there is…
Two years ago I reported on the use of the elliptical curve cryptographic algorithm in generating digital signatures for securing the DNS (DNSSEC) (http://www.potaroo.net/ispcol/2014-10/ecdsa.html). The conclusion at the time was hardly encouraging: “Will ECDSA ever be useful tool for DNS and DNSSEC? As good as ECDSA is in presenting strong…
Bruce Schneier’s recent blog post, “Someone is Learning How to Take Down the Internet”, reported that the incidence of DDOS attacks is on the rise. And by this he means that these attacks are on the rise both in the number of attacks and the intensity of each attack. A…
by Joao Luis Silva Damas and Geoff Huston In the original framework of the IP architecture, hosts had network interfaces, and network interfaces had single IP addresses. The list of active network interfaces, and the manner in which they acquire IP addresses, either by a static configuration or by…
Every so often I hear the claim that some service or other has deliberately chosen not to support IPv6, and the reason cited is not because of some technical issue, or some cost or business issue, but simply because the service operator is of the view that IPv6 offers an…
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 sessions that are relevant and interesting to them. I do much the same when I attend IETF meetings, and from…
There are a number of ways to view the relationship between hosts and the network in the Internet. One view is that this is an example of two sets of cooperating entities that share a common goal: hosts and the network both want content to be delivered. Both have an…
