The proposal to stop recalculating the internet’s zone-file changes
zonedata.org proposes that ICANN’s Centralized Zone Data Service distribute verifiable daily changes to authorized zone-file recipients.
Field notes
The draft targets a specific inefficiency in CZDS: every authorized consumer currently receives the full daily snapshot and independently derives the delta. Its proposed change record would cover additions, deletions, and delegation changes while preserving the full files as a baseline and audit fallback. The site identifies the document as version 0.9, prepared for discussion at ICANN87, and names Leo Angelo and Hafiz Farooq as authors. It also states that the resource is non-commercial and does not track visitors.
