Lead architect for GoDaddy’s RDAP/WHOIS systems used across its global registrar portfolio. RDAP (Registration Data Access Protocol) is the modern, structured replacement for WHOIS, providing authoritative information about domain name ownership, status, and contact details.
System Context: Authoritative Registration Data
System Characteristics
- Globally distributed
- High availability
- Low latency
- Multiple registrars
- Protocol compliance
- Regulatory/Privacy
Architectural Challenges
Operating RDAP and WHOIS at this scale introduces severe constraints. Authoritative systems must remain eventually consistent across geographical boundaries while maintaining extremely low read latency for global Internet-facing abuse and load.
Furthermore, privacy regulations (such as GDPR) require dynamic policy evaluation per request, varying by registrar, TLD, and client authorization level. Backward compatibility with decades of legacy WHOIS clients must be maintained alongside modern JSON-based RDAP responses. Operational failover across global regions must happen transparently to external clients querying the infrastructure.
Why this matters to my current work
RDAP, DNS, registrar systems, and modern agent identity systems share identical structural problems: they require independent parties to manage identity, assert authority, handle distributed ownership, and rely on strict protocol interoperability across globally distributed state.
The architectural rigor required to keep global domain registration data consistent, secure, and available directly translates to designing verifiable trust infrastructure for autonomous agents.
