WHOIS Lookup
Look up domain registration information using public RDAP APIs. Check registrar, expiration date, name servers, and more. Uses cloud-based processing.
How to Use the WHOIS Lookup
Similar Tools You Might Need
See allDomain Availability Checker
Check a domain name across major TLDs against authoritative RDAP servers — a missing record means likely available. TLDs without RDAP fall back to a DNS heuristic. Always confirm with a registrar before purchasing.
SSL Checker
Check SSL/TLS certificate details for any domain via public certificate APIs. View issuer, validity period, days remaining, and SANs. Expiry alerts catch outages before users do — free, no signup.
Subdomain Finder
Discover subdomains via public certificate records plus live DNS checks of common names. Read-only lookups run from your browser — the domain you check is visible to crt.sh and Google DNS, as with any lookup.
IFSC Code Lookup
Looks up bank details from an 11-character IFSC code — bank name, branch, address, city, district, and contact info. Live lookup via the Razorpay IFSC API.
Indian Age Calculator
Calculate exact age in years, months, and days from day-month-year dropdowns with a target date. Includes eligibility check for Indian government age requirements.
Frequently Asked Questions
What information does the WHOIS lookup return?
Domain registrar name, registration and expiration dates, name servers, DNSSEC status, and the RDAP registry where the domain is managed.
What's the difference between WHOIS and RDAP?
WHOIS is the legacy protocol. RDAP (Registration Data Access Protocol) is the modern replacement that provides structured JSON data and respects privacy laws by redacting personal info.
Can I look up any TLD?
Most generic TLDs (.com, .net, .org) and many country-code TLDs are supported. Some ccTLDs may have limited data depending on the registry's RDAP implementation.
Why is registrant contact info redacted?
GDPR and other privacy regulations require registries to hide personal contact details. The lookup shows the registrar and public data, but personal info is masked.
Is the lookup query stored?
No. Lookups go through a first-party RDAP proxy plus public RDAP/whois providers, so the queried domain is visible to those providers. No search history is stored on our server.
How long does a lookup wait, and how much history is kept?
Each provider gets 15 seconds before the tool moves on — first-party RDAP first, then rdap.org, then the whois fallback. The recent-lookups row keeps your last 5 domains for one-click re-checks.
