From the very early concepts of it’s just like IPv4, only with a 128-bit address field”, through the models of Aggregation Identifiers” and the hierarchy of Top-Level,” Next-Level” and Site-Level” defined in RFC 2373 from July… DNSSEC and .nz 17 Apr 2024 in DNS , Operations I had the opportunity to participate in the New Zealand Network Operators Group meeting (NZNOG) in Nelson earlier this month. This article was prompted by a presentation from Josh Simpson on an .nz service outage incident in May 2023. I guess we’ve become used to reading evasive and vague outage… Coherent Optical Transceivers 14 Apr 2024 in Technology I had the opportunity to participate in the New Zealand Network Operators Group meeting (NZNOG) in Nelson earlier this month. This article was prompted by a presentation from Thomas Weible of Flexoptix at NZNOG on the topic of Coherent Optical Transcievers. The first generation of optical transmission systems used simple… DNS Topics at IETF 119 27 Mar 2024 in DNS , IETF The Internet has changed quite radically in recent years. The proliferation of service and content delivery platforms at the edge of the network, fed by privately operated feeder networks has reamed out the transit core of the Internet. Most of the traffic and the overwhelming of value within the Internet… Adding IPv6-only to DNS and Truncation in UDP 13 Mar 2024 in DNS In February I looked at the behaviour of the DNS when processing responses in UDP which set the Truncated flag in the DNS response. In particular, I was looking for the incidence of DNS resolvers which used the Answer section in truncated responses (despite the admonition in DNS standards not… KeyTrap! 11 Mar 2024 in DNS , Security The National Research Center for Applied Cybersecurity ATHENE has uncovered a critical flaw in the design of DNSSEC, the Security Extensions of DNS (Domain Name System). DNS is one of the fundamental building blocks of the Internet. The design flaw has devastating consequences for essentially all DNSSEC-validating DNS implementations and… Opinion: Digital Sovereignty and Internet Standards 4 Mar 2024 in Policy There have been a number of occasions when the Internet Engineering Task Force (IETF) has made a principled decision upholding users’ expectations of privacy in their use of IETF-standardised technologies. (Either that, or they were applying their own somewhat liberal collective bias and to the technologies they were working on!)… DNS and Truncation in UDP 26 Feb 2024 in DNS I’ll press on here with another item within an overall theme of some current work in DNS behaviours with a report of a recent measurement on the level of compliance of DNS resolvers with one aspect of standard-defined DNS behaviour: truncation of DNS over UDP responses. The DNS leverages the… DNS OARC 42 11 Feb 2024 in DNS , Operations – The DNS Operations, Analysis, and Research Center (DNS-OARC) brings together DNS service operators, DNS software implementors, and researchers together to share concerns, information and learn together about the operation and evolution of the DNS. They meet between two to three times a year in a workshops format. The most… DNS and the DELEG Proposal 7 Feb 2024 in DNS The Internet’s Domain Name System (DNS) is implemented as a distributed database. The structure of the database mimics the structure of the name space itself, namely a hierarchy where each node” (or zone”) in the distributed database has a single parent” node and some number of child” or descendant nodes… Post navigation ← Older posts APNIC MyAPNIC Training Conferences Labs APNIC Asia Pacific Network Information Centre Contact us research@apnic.net Tel: +61 7 3858 3188 © 2015 APNIC |...
