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 satisfy their Whois obligations using different services. The two common models are often characterized as "thin" and "thick" Whois registries. This distinction is based on how two distinct sets of data are managed. 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. A thin 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. 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. COM and NET are examples of thin registries. Thick registries maintain and provide both sets of data (domain name and registrant) via Whois. INFO and BIZ are examples of thick registries.
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'.
