Centralized Zone Data Service (CZDS)
The Centralized Zone Data Service provides a centralized point for interested parties to request access to Zone Files provided by participating Top Level Domain Registries. The service is the solution for scaling zone data transfer as hundreds of new gTLDs are added to the Internet.
Every new gTLD Registry is required to provide zone data to approved requesters (e.g. law enforcement agents, IP attorneys, researchers) upon technical delegation of its gTLD.
New Registries will be provided with instructions for utilizing the Centralized Zone Data Service once a gTLD Registry Agreement has been executed.
CZDS for End Users
- The Centralized Zone Data Service has been created to simplify the process for end-users to request zone data and enter into individual and standardized agreements with the registries that provide TLD Zone Files.

CZDS for Registries
- CZDS simplifies the process of entering into zone data contracts. Rather than creating and executing a contract for every request, Registries can simply approve or deny requests with one click.
- Registries can save additional time by appointing ICANN to handle zone data file transfer (AXFR), formatting, and distribution to approved end-users instead of using internal resources.
