[Podcast] DNS query duplication
Why does APNIC Labs experimental systems see almost all DNS queries twice or more?
Data synchronization
Distributed systems depend on synchronization, but every approach has tradeoffs. From full copies to delta updates, how do you choose the right method?
[Podcast] Testing RSSAC 028 DNS root server name choices
A measurement study of how the DNS bootstrap priming query behaves when the root servers are renamed and DNSSEC signatures are added.
DNS query duplication
In the DNS, name resolution space queries are free. To what extent do we see over-querying on the part of recursive resolvers in the DNS?
Unveiling the hidden complexity of authoritative DNS resilience
Guest Post: Government online services rely on authoritative DNS as a critical foundation of national digital infrastructure. This study presents a systematic framework to assess DNS resilience, revealing strengths, weaknesses, and operational practices shaping governments’ ability to withstand failures and attacks.
Cold start DNS
There is an obvious tension between resilience and speed in the design of a resolver’s query strategy. DNS cold starts bring that tension into focus.
Centrality in the Internet’s names
The Internet’s Domain Name System undertakes a vitally important role in today’s Internet. The question here is — is the DNS centralized?
Authoritative DNS over encrypted transport at OARC 45
The use of encrypted DNS transports for communication between recursive resolvers and authoritative services in the DNS was an important topic of discussion OARC 46 in Edinburgh.
