RDAP Lookup

Check up to 10 domains at once. For each one you get its registry status, expiry & registrar (live RDAP), DNS records, the live SSL certificate, and Wayback Machine history — the modern successor to WHOIS.

RDAP status & datesDNS recordsSSL certificateWayback historyLifecycle forecast

One domain per line (or comma-separated), up to 10. Supports .com, .net, .org, .io, .dev, .app, .ua, .de, .ai and hundreds of other TLDs via IANA Bootstrap.

What is RDAP?

The Registration Data Access Protocol — the modern replacement for WHOIS

1

Standardized JSON format

Unlike WHOIS (plain text, inconsistent), RDAP returns structured JSON data that is easy to parse and machine-readable. Defined by IETF RFC 9083.

2

Direct registry queries

RDAP queries the authoritative registry server directly — Verisign for .com/.net, PIR for .org, Identity Digital for 200+ new TLDs. Data comes straight from the source.

3

More than just registry data

Alongside RDAP status, this tool resolves live DNS records, reads the SSL certificate served on port 443, and pulls Wayback Machine history — a full picture of each domain in one query.

RDAP Status Guide

What each domain status means and what action to take

Registered
Active — domain is registered and owned
The domain has a current registrant. RDAP returns full data: registrar, expiry date, nameservers. Cannot be registered by others.
Redemption
Expired — previous owner can still reclaim
The domain expired and entered the redemption grace period (typically up to 30 days). The previous registrant can still renew at a higher cost. If not renewed, it proceeds to pending delete.
ID Grace
Identity Digital extended grace period
Some registries (Identity Digital: .online, .site, .store, 267+ TLDs) add an extra grace period after expiry. The domain is held for ~30 days before entering pendingDelete.
Pending Delete
Drop imminent — will be released within 1-5 days
The domain is in its final deletion countdown. It cannot be renewed. Within 1-5 days it will be deleted from the registry and become available for registration.
Available
RDAP returned 404 — domain has dropped from the registry
The RDAP server returned HTTP 404, meaning the domain is not in the registry. It may be available for registration through any registrar.
