RDAP & WHOIS Lookup, enriched with live domain intelligence.

Enter any domain name (such as example.com) into the search box above. DomainKits queries the authoritative registry live and returns a structured profile covering four dimensions:

• Registration & Lifecycle Timeline: Exact registration date, calculated domain age, last update timestamp, and days remaining until expiration.
• Cross-TLD & Keyword Activity: How many gTLDs and ccTLDs are registered for the same string, automatic word-split detection, and recent counts of newly registered, listed, expired, and dropped domains sharing those keywords.
• Registry & Nameserver Footprint: Sponsoring registrar, abuse contact, decoded EPP status badges, and assigned nameservers, complete with the total number of domains hosted on each nameserver.
• Live DNS & ASN Routing: Current A, AAAA, MX, and text records paired with IP geolocation, TTL, and Autonomous System Number (ASN) ownership.

RDAP (Registration Data Access Protocol) is the modern, standardized replacement for legacy port-43 WHOIS mandated by ICANN. Instead of returning unstructured plain text, RDAP delivers machine-readable JSON directly from registries over HTTPS.

Under the EU General Data Protection Regulation (GDPR) and modern registry privacy standards, personal registrant contact details (name, email, phone, and street address) are redacted by default. However, critical operational and valuation signals, such as domain age, multi-year expiration horizons, registrar identity, EPP lock statuses, and DNS infrastructure, remain public and fully visible in your lookup.

Beyond checking whether a name is taken, a domain's registry record reveals how securely it is held and whether it might change hands:

• Security Locks ("Locked" Badge): Status codes like clientTransferProhibited, clientDeleteProhibited, and clientUpdateProhibited mean the domain is actively protected against unauthorized transfers or accidental deletion. A domain carrying these client locks is typically a well-managed asset.
• Hold & Expiration Warnings: If a record shows clientHold, serverHold, redemptionPeriod, or pendingDelete, the domain is either suspended for policy/payment issues or actively moving through the expiration pipeline. For a full breakdown of every code, see our Domain Status Guide.
• Update vs. Expiration Gap: A Last Update timestamp that aligns with a multi-year future Expiration Date indicates a recent renewal commitment, whereas a domain approaching expiration with no recent update may be a candidate to watch.
• Cross-TLD Saturation: Seeing that a domain's exact keyword is registered across 100+ gTLDs and ccTLDs points to strong global demand, a key signal before clicking Make Offer or pursuing an acquisition.

Every lookup result gives you direct paths to act on a taken domain or find an alternative:

• Monitor or Make an Offer: Click Add email alert at the top of the result card to track the domain on Domain Monitor and get notified if its status, expiration, or DNS changes, or, when the domain is listed for sale, use Make Offer to initiate an acquisition inquiry.
• Explore Keyword Activity Cards: Every lookup automatically splits the domain into its root keywords and displays clickable counters for Newly Registered, Newly Listed (For Sale), Newly Expired, and Newly Dropped variations, letting you jump straight to available or purchasable alternatives containing the same words.
• Check Open Extensions: Click the TLDs Registered counter or run a TLD Search to see which of the 1,200+ gTLD and ccTLD extensions remain open for immediate registration.

At the bottom of every WHOIS result, the Dig Deeper bar connects your lookup to the rest of the DomainKits intelligence suite:

• One-Click Deep Dives: Pivot directly from a WHOIS record to Subdomain Finder (certificate transparency enumeration), Backlinks Checker, Typosquat Scanner (look-alike domains), or Reverse NS by clicking any nameserver domain count.
• MCP server and Agent Skills: let AI assistants and security agents run WHOIS, DNS, and domain intelligence lookups for you. See MCP and Agent Skills.
• REST API, n8n & Python SDK: integrate automated domain lookups and lifecycle monitoring directly into your scripts and security workflows. See the API docs.
