PDP Thick WHOIS

For the generic top-level domain (gTLD) registries, ICANN specifies WHOIS service requirements through the registry agreements (ICANN 2009 Registry Agreements) and the Registrar Accreditation Agreement (RAA). Registries have historically satisfied their WHOIS obligations under two different models, often characterized as "thin" and "thick" WHOIS registries. This description is based on how the two distinct sets of data are maintained.
One set of data is associated with the domain name, and a second set of data is associated with the registrant of the domain name. In a thin registration model, registry only stores and manages the information associated with the domain name. This set includes data sufficient to identify the sponsoring registrar, status of the registration, creation and expiration dates for each registration, name server data, the last time the record was updated in its WHOIS data store, and the URL for the registrar's WHOIS service. The registry publishes that information and maintains certain status information at the registry level. With thin registries, registrars manage the second set of data associated with the registrant of the domain and provide it via their own WHOIS services, as required by Section 3.3 of the RAA 3.3 for those domains they sponsor.
In a thick registration model, the registry maintains and provides both sets of data (domain name and registrant) from the registrar and publishes that data via WHOIS.
The GNSO Council requested an Issue Report on 'thick' WHOIS at its meeting on 22 September 2011 noting that the Issue Report should "not only consider a possible requirement of 'thick' WHOIS for all incumbent gTLDs in the context of IRTP, but should also consider any other positive and/or negative effects that are likely to occur outside of IRTP that would need to be taken into account when deciding whether a requirement of 'thick' WHOIS for all incumbent gTLDs would be desirable or not."
On 14 March 2012, the GNSO Council initiated a PDP to consider a possible requirement of thick WHOIS for all gTLDs. The PDP working group finalized its report and submitted it to the GNSO Council on 21 October 2013. The GNSO PDP working group recommends all gTLD registries to provide thick WHOIS services with a consistent labeling and display (CL&D). It would improve the stability of and access to WHOIS data, as well as potentially reduce acquisition and processing cost for consumers of WHOIS data. During its meeting on 31 October 2013, the GNSO Council unanimously adopted the recommendation to require thick WHOIS for all gTLD registries. Following the Public Comment forum and the Governmental Advisory Committee (GAC) notification, the ICANN Board considered and adopted the recommendations during its meeting on 7 February 2014.
The CL&D of the Registration Data Directory Service (RDDS) Output for All gTLDs policy has completed implementation by the policy effective date of 1 August 2017.
For the Thick WHOIS Transition Policy for .com, .net, and .jobs, on 7 November 2019, the ICANN Board passed a Resolution to defer contractual compliance enforcement. ICANN Contractual Compliance will defer enforcement of the Thick WHOIS Transition Policy until all of the following have occurred:
- the gTLD Registration Data Policy Implementation Review Team (IRT) completes its review and establishes an implementation timeline estimate of the Expedited Policy Development Process (EPDP) Team on Temporary Specification for gTLD Registration Data's Phase 1 recommendations as adopted by the ICANN Board on 15 May 2019;
- ICANN org and the IRT provide the GNSO Council with the required information on the impacts of the EPDP Team's recommendations on existing policies and procedures (including the Thick WHOIS Transition policy); and
- the GNSO Council makes a determination on whether to take action on updates to relevant policies and procedures (which could include additional policy work, guidance, or other actions to be determined) impacting the Thick WHOIS Transition Policy.
For avoidance of doubt, the Thick Whois Transition Policy for .COM .NET and .JOB has been in effect since 1 February 2019. The board resolution pertains to the compliance enforcement action only.
