Future Directions for DNS: Exploring Distribution, P2P, and Centralization

This presentation by Tim Deegan at the HEAnet Conference in November 2005 discusses innovative ideas for the future of the Domain Name System (DNS). Key topics include addressing current and future issues, altering DNS architecture, and maintaining client and protocol integrity. The talk outlines three potential approaches for the DNS: distributing all data widely, implementing a peer-to-peer model, and centralizing system complexity. References to prior research are also provided, highlighting the importance of evolving DNS to meet modern demands.

  1. DNS: Brave new worlds Tim Deegan tim.deegan@cl.cam.ac.uk HEAnet conference November 2005

  2. Academic ideas on the future of the DNS: • Fixing current/future problems – with science! • Changes to the architecture of the DNS. • Keeping the clients and the protocol. • Not: • IETF work: DNSSEC, EDNS*, new types. • Non-DNS name services: Active Names et al. • DNS measurement.

  3. The DNS: boxes and arrows ie root þ ? þ dcu.ie

  4. 1. Distribute! þ þ þ þ þ dcu.ie þ ?

  5. 2. Peer-to-peer! þ ?

  6. 3. Centralize! þ þ þ ?

  7. In summary Three possible new directions for the DNS • Distribute: copy everything everywhere • P2P: shuffle everything around • Centralize: move the complexity Will we see any of this? Up to you…
