Domain Ownership WHOIS: essential concepts

This guide covers what really matters in domain Ownership WHOIS: concepts, context, limits and interpretations that often cause confusion.

Technical lookup

Quick examples

Use the search box to inspect an Internet asset.

You can query a domain, an IP, an ASN or an RDAP entity handle. The response tries to combine the most useful public signals from registration, events, contacts and DNS without turning the page into a noisy junk drawer.

The lookup runs on our server with timeout, short cache, SSRF protection and without storing the query in analytics. Analytics events only record aggregate tool usage, never the searched value.

Full tool FAQ

How should I use this tool without reading the result too superficially?

Start with the object type, then review events, statuses and entities. Only then inspect raw data. The common mistake is staring at one field while ignoring the combination of registrar, timeline, range, ASN, notices and DNS.

Does the tool store the searched value?

What is RDAP and why is it preferable to classic WHOIS?

Does WHOIS still matter if RDAP exists?

What do statuses such as clientTransferProhibited and serverHold mean?

If RDAP has no response, does that mean the domain is available?

Why would I query an ASN instead of a domain?

Why is DNS shown together with registration data?
