Am I really talking to you? In a networked world that’s an important question. For example, where I’m located, when I look up the DNS name www.google.com I get the IPv6 address 2404:6800:4006:813::2004. This implies that when I send an IPv6 packet to this destination address I will reach a…
There was an interesting discussion in a working group session at the recent IETF 111 meeting over a proposal that this working group should require at least two implementations (presumably independently developed implementations) of a working group draft before the working group would consider the document ready for submission to…
I’ve already scribed my thoughts on the DNS-related topics that were discussed at the July 2021 IETF 111 meeting. It may be surprising to the DNSphiles out there but there really are other topics that are discussed at IETF meetings not directly related to the DNS! These are some notes…
IETF 111 was held virtually in July 2020. These are some notes I took on the topic of current activities in the area of the Domain Name System and its continuing refinement at IETF 111. DNSOP – DNS Operations DNSOP is the general working group for most DNS topics and…
The Border Gateway Protocol (BGP) is the Internet’s inter-domain routing protocol, and after some thirty years of operation BGP is now one of the more venerable of the Internet’s protocols. One of the major ongoing concerns related to BGP is its lack of effective security measures, and as a result…

One of the major ongoing concerns related to BGP is its lack of effective security measures, and as a result…
Much has been said about the criticality of the small coterie of large-scale content distribution platforms and their critical role in today’s Internet. These days when one of the small set of core content platforms experiences a service outage then it’s mainstream news, as we saw in June of this…
The Swedish carrier group Telia has recently announced the sale of its international wholesale business to Polhelm Infra, an infrastructure investment manager jointly owned by a number of Swedish pension funds. Why would a telco operator sell off what was a core part of its operation to a pension fund?…
On the afternoon June 17 of this year there was a widespread outage of online services. In Australia it impacted three of the country’s largest banks, the national postal service, the country’s reserve bank, and one airline operator. Further afield from Australia the outage impacted the Hong Kong Stock Exchange,…
The world of cryptographic algorithms is one that constantly evolves. In part, this evolution is required by the nature of the process. The practical objective of these algorithms is not to pose a problem that is insoluble, but to pose a problem that is computationally infeasible. For example, a problem…
