Free RDAP Lookup

Run an RDAP lookup for any domain. The Registration Data Access Protocol returns structured JSON for registrar, status, events, entities, and DNSSEC. The modern replacement for WHOIS.

What you get

Everything in one report.

  • 01

    Structured fields

    Registrar, entities, events, and status arrive as typed JSON, not free form text, so every value lands in the right place.

  • 02

    Standardized status

    RDAP uses a fixed vocabulary of status and event types, which digga decodes into plain language.

  • 03

    IANA bootstrap discovery

    digga finds the correct RDAP server for each TLD through the official IANA bootstrap registry.

  • 04

    Raw JSON toggle

    Read the clean record or flip to the raw RDAP response to inspect every field the registry returned.

What is RDAP?

The Registration Data Access Protocol is the modern, JSON based successor to WHOIS, defined in RFC 7480 and related standards. Every registry runs an RDAP server, discoverable through the IANA bootstrap registry, that returns registration data as structured objects. Because the response is typed JSON rather than free form text, an RDAP lookup is far more reliable to parse and display than classic WHOIS.

RDAP vs WHOIS

WHOIS returns plain text that varies from registrar to registrar, which makes it fragile to read consistently. RDAP returns the same information as standardized JSON with defined field names, status values, and event types. It also supports secure transport and internationalization. RDAP is gradually replacing WHOIS across the registry world, so digga queries it first and only falls back to WHOIS when a registry has not adopted it yet.

How RDAP discovery works

There is no single RDAP server for every domain. Each TLD operator runs its own. digga looks up the right server in the IANA bootstrap registry, then queries it directly for the domain you entered. That is the same mechanism RDAP clients and the registry ecosystem rely on, so the data you see comes straight from the authoritative source.

What you get back

A normalized record with the registrar and its IANA ID, registration and expiration events, domain status codes, nameservers, and DNSSEC state. Where the registry redacts contact details for privacy, digga shows what remains and lets you open the raw RDAP JSON to see the complete response.

FAQ

Questions, answered.

Is this RDAP lookup free?
Yes, completely free with no signup. digga is open source under AGPL 3.0.
What is RDAP?
RDAP, the Registration Data Access Protocol, is the modern JSON based replacement for WHOIS defined in RFC 7480. It returns structured registration data from the registry RDAP server for each TLD.
Is RDAP replacing WHOIS?
Yes, gradually. RDAP returns standardized, machine readable JSON and is being rolled out across registries. digga queries RDAP first and falls back to WHOIS where RDAP is not yet available.
Which TLDs support RDAP?
Most generic TLDs and a growing number of country code TLDs run an RDAP server, discoverable through the IANA bootstrap registry. digga finds the right server automatically.
Can I see the raw RDAP response?
Yes. The record view shows the clean, structured fields, and a toggle reveals the raw RDAP JSON exactly as the registry returned it.
