SiteTraceKit Glossary
What is RDAP?
RDAP is a structured way to access public domain registration information from registries and registrars.
Short definition
The Registration Data Access Protocol can provide fields such as registrar, registration date, expiration date, nameservers and domain status.
Simple example
A .com RDAP response may include a registrar name, creation date, expiry date, status codes and authoritative nameservers.
Why it matters for website checks
RDAP can help place domain age and registration signals in context without showing personal WHOIS contact records.
Limits
Not every registry returns the same fields. Missing RDAP data does not prove anything about the operator or the website content.
What does this mean for website owners?
Use the signal as a starting point for manual review. The website’s purpose, technical environment and actual configuration provide the necessary context.

FAQ
Is RDAP the same as WHOIS?
It serves a similar purpose but is more structured and web-friendly than classic WHOIS.
Does SiteTraceKit show personal contact data?
No. Reports focus on neutral fields such as dates, registrar, nameservers and status where available.
Why can RDAP be unavailable?
The registry may not expose the field, the lookup can time out or the domain may use a TLD with limited public data.
