Running Code

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…


Some not-DNS Topics at IETF 111

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…


DNS at IETF 111

In Australia it impacted three of the country’s largest banks, the national postal service, the country’s reserve bank, and one airline operator.

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…


Internet Centrality

The IRTF is a research-oriented part of the larger IETF structure. It has a number of research groups, one of which, DINRG, is looking at decentralized Internet Infrastructure. That’s a big topic, and one could certainly look at distributed decentralized blockchain frameworks applied to ledgers, used by Bitcoin and similar,…
