ICANN64 | Day 2 – Root Server Operations (How it works)

Exclusive Coverage by Tarun Taunk, Chief Editor ITVoice

This session from the Root Server System Advisory Committee (RSSAC) was divided into four subsections 1. The overview of DNS 2. A quick explanation of Anycast and how it works 3. Root server System today and its features. 4. RSSAC and some recent RSSAC activities.


Mr Andrew McConachie started with a brief overview of the Domain Name System (DNS), then he talked about IPv4 and IPv6 addresses and its history and what the root zone operators do, which included the Root Zone Administrator and Maintainers. Further, in the session he explained what Anycast allows us to do, we can have multiple instances serve the same data to all sources and
the sources reach different destinations based on intermediate routing policies, and the idea is that the sources can get the data faster through lower latencies and that also the DDoS attack traffic is sent to the closest instance, thereby being distributed so it shouldn’t overwhelm a single server.

Then Mr Andrew McConachie called Mr Carlos Reyes to continue the session and to talk about RSSAC and RSSAC Caucus also its recent activities including current work and recent publications. He explained what is RSSAC? RSSAC is the Root Server System Advisory Committee as he mentioned, and its mission is to advise the ICANN Board and Community on matters relating to the operation, administration, security, and integrity of the root server system. He continued and explained how RSSAC works and how one can be a part of it, also mentioned that RSSAC Caucus has 106 members currently and at the end, the session was opened for questions from the attendees.

For any doubts, any RSSAC member or ask-rssac@icann.org were to be contacted.
