WHOIS / RDAP Domain Lookup
Check domain registration, expiration date, registrar locks, and DNSSEC status using live registry RDAP data.
Best for domain owners, IT teams, and security reviews auditing renewal risk, registrar lock coverage, and domain hijacking exposure across a portfolio.
What This Tool Checks
- Expiration and renewal risk alerts
- Transfer lock and hold status review
- DNSSEC delegation verification
Why It Matters
An expired or hijacked domain takes the website, email, and certificates down with it. Registration-level controls like transfer locks, auto-renewal, and DNSSEC are the cheapest protection a domain owner can buy, and RDAP shows exactly which ones are missing.
Best For
Best for domain owners, IT teams, and security reviews auditing renewal risk, registrar lock coverage, and domain hijacking exposure across a portfolio.
What To Do Next
Use the result to renew anything close to expiry, enable the registrar transfer lock, and turn on DNSSEC where the registry and DNS host support it.

What does the WHOIS / RDAP Domain Lookup look for?
WHOIS / RDAP Domain Lookup focuses on expiration and renewal risk alerts, transfer lock and hold status review, dnssec delegation verification. It is designed to help teams identify this category of weakness quickly and then move into broader workflows if deeper follow-up is needed.
What is the difference between Quick and Comprehensive mode?
Quick mode stays public for focused diagnostics. Comprehensive mode is intended for authenticated workflows where users need saved history, richer follow-up, and broader account-linked execution.
When should I use the full Vulnify platform instead?
Use the full platform when you need more than one focused diagnostic, want to keep reports and history, or need scheduled scans, exports, and broader vulnerability coverage beyond whois / rdap domain lookup.
