The "Fundamental Obligations" are designed to ensure a competitive, fair, and stable domain name market.
1. Non-Discriminatory Access
This is the "Golden Rule" of the registry-registrar relationship. A Registry Operator must treat all ICANN-accredited registrars equally.
- Equal Treatment: You cannot offer a lower wholesale price or better technical support to one registrar while charging others more.
- Uniform Terms: All registrars must sign the same Registry-Registrar Agreement (RRA).
- Fair Promotion: If you offer a "sale" or marketing incentive, it must be available to every accredited registrar who wishes to participate.
2. The Registry-Registrar Agreement (RRA)
A Registry cannot simply make up its own rules on the fly.
- ICANN Approval: Any RRA must be consistent with the Base RA. If a Registry wants to make "substantive" changes to its RRA, it must submit those changes to ICANN for a review period (and often a public comment period).
- Transparency: The RRA must clearly outline the technical requirements, payment terms, and compliance standards the registrar must meet.
3. Technical Interoperability (The Shared Registration System)
Registries are obligated to provide a stable Shared Registration System (SRS) that registrars use to register and manage domains.
- EPP Standard: Registries must support the Extensible Provisioning Protocol (EPP), the industry-standard "language" used for domain transactions.
- Performance Specifications: The Registry must meet strict "Service Level Agreements" (SLAs). For example, the SRS must be available 99.4% to 99.9% of the time to ensure registrars can always process orders.
4. Data Handling and WHOIS/RDAP
Registries must maintain an accurate database of all registered domains and provide access to that data.
- Registration Data Directory Services (RDDS): Registries must provide a publicly queryable database (via WHOIS or the newer RDAP protocol) so that registrars and the public can verify domain ownership and status.
- Data Escrow: Registries must regularly "back up" their registration data with a third-party escrow provider. This ensures that if the Registry fails, the registrars (and their customers) don't lose their domains.
5. Vertical Integration Safeguards
If a company owns both a Registry and a Registrar (known as Vertical Integration), there are strict "Code of Conduct" obligations:
- Anti-Abuse: The Registry cannot use its "insider" data to give its own registrar an unfair advantage (e.g., seeing which domains are being searched for and registering them first).
- Separation of Systems: The Registry must maintain clear boundaries to ensure that its wholesale operations don't unfairly subsidize its retail arm.
