Registration and identity claims
WHOIS and RDAP describe registration records. They do not prove who writes a website. Start with the privacy and redaction guide when public contact fields are missing.
Direct answer: These guides explain how registration, DNS and lifecycle evidence is collected. They show what each field can establish and which conclusions require another source.
Guides built for a decision, not a keyword
Each guide separates observable evidence from inference. It includes a worked interpretation, handles edge cases, and links to the primary protocol or policy behind the conclusion.
Begin with what WHOIS can establish, then compare it with structured RDAP evidence. Follow the DNS delegation chain when the investigation moves from registration to live infrastructure.
Choose the evidence path that matches your question
DNS and delegation failures
Parent and child DNS data describe name resolution. Use the DNS records reference to connect each record type to a diagnostic question. Follow the DNS migration runbook before a provider cutover.
Lifecycle and operational changes
Events and status codes describe registry operations. Read the EPP status code explanation before acting on a lock, and follow the domain expiration timeline before treating one date as a release promise.
