WHOIS & RDAP Lookup
Look up any domain's registrar, registration and expiry dates, nameservers, and status codes. Live RDAP with WHOIS fallback.
What you get
This lookup reads the same live registry data that powers shadom.co monitoring. It queries RDAP, the modern structured replacement for WHOIS, and falls back to WHOIS for TLDs that have not migrated. You see the registrar, key dates, nameservers, and the raw status codes that tell you whether a domain is locked, expiring, or already on its way to dropping.
Frequently asked questions
What is a WHOIS lookup?
A WHOIS lookup returns the public registration record for a domain: who registered it, which registrar manages it, when it was created and when it expires, its nameservers, and its status codes. This tool queries the modern RDAP protocol first and falls back to classic WHOIS for TLDs that have not migrated yet.
What is the difference between WHOIS and RDAP?
WHOIS returns unstructured text that varies by registrar; RDAP returns standardized JSON over HTTPS and is the ICANN-mandated replacement. RDAP also supports differentiated access and internationalized data. This tool uses RDAP wherever a registry supports it and shows which protocol answered under the result.
Why is the registrant name or contact hidden?
Since GDPR, most registries redact personal registrant details in public WHOIS and RDAP responses. You will usually see the registrar, dates, nameservers, and status codes, but the registrant is often a privacy service or simply omitted. Organization-level registrants are sometimes still shown, which is why this tool surfaces the registrant organization when present.
What do domain status codes mean?
Status codes like clientTransferProhibited or pendingDelete describe what a registry currently allows or is doing with a domain. Prohibited codes are usually normal locks that protect the domain. Codes such as redemptionPeriod or pendingDelete mean the domain has expired and is moving toward becoming available again.
How do I get notified when a WHOIS record changes?
Create a free shadom.co account and add the domain to your watchlist. You get an email, push, or webhook alert whenever its registrar, nameservers, registrant, status codes, or expiry date change, so you catch transfers, drops, and hijack attempts without re-checking by hand. The free plan covers up to 100 domains.
