ICANN does not formally use the term "restricted" as it relates to TLD types. However, in general, a TLD that has restrictions on eligibility will differ from a "Closed or Exclusive Use TLD" in that registration of domain names within the TLD is not limited to only the registry operator and Affiliates; instead, registration is limited to a particular group defined by the registry operator (e.g., a community or registrants within a specific geographic area).
